Are you doing a new state of the art design in ASIC or just using special components ? The question seems too vague to get a straight answer, but generally speaking its design specifications seems almost infeasible.
I need to code to program pic16f84a to increament from 0 to a number(like 11), when it reaches the highest number, it go back again and the increament are display using two seven segment display
Is their an electrolytic start up cap that has degraded in capacitance due to age?…try replacing it. Sorry I cannot hear your video - - - Updated - - - Was the power supply ever working? What voltage do you have on the vdd pin of the uc3845 when it is not working? Do you have 5v
If you look closely, you'll realize that the output of your (crummy) peak detector is actually a fraction of the actual peak value, maybe 50%. When that second peak comes along the cap has already been charged to a value greater than 50% of the new peak. You might want to consider using an active (opamp) peak detector, and perhaps changing the
It looks like Cadence has "moved on" from supporting the original layout-based PCells and is failing to evaluate? That's pretty crappy. You might have too crusty a lib, for the brave new modern world? Do you have access to an older version that wasn't so unfriendly to legacy libraries? Or, to some facility for converting layout based PCells
Hello All, I am very new to System verilog and I do not understand the code below. i.e. after 1 bit hold and 128 bit Out has been declared as logic, what is CGlobal CGlobal(); means ? Also after that, what does the assign statements do here. i.e. clkA is assigned to CGlobal.clkA is it an array ? if it is then, how is the indexing happening here
Pickit2 will generate a new OSCCAL value for the device if you tell it to. look under the 'Tools' in the Pickit window. It calibrates the internal 4MHz oscillator, not the RC one. The error message is generated when the 'RETLW xx' instruction at address 0x3FFF is overwritten by your own program or is erased. That address is reserved for holding th
Hello guys. First time poster on here. I want to program some new key fobs to my car's remote central locking. The problem is all keys have a 4 digit code that I don't have. the only way to unlock the remote central locking receiver for programming new keys is to use a 4 digit code from a key fob already linked to the receiver. Now I know there's a
Most of the Pakistanis look for suitable car, which they want to buy keeping in view the built, features. Various automobile manufacturing companies carried out their business by providing new models in market with their impressive features. 5. Suzuki Cultus It is shocking news that people looked for this short vehicle and (...)
Hi, I'm new to innovus. From where I can get the help which are related to innovus tool. Please help me. Thanks.
If it is, they are fairly easy to repair but I doubt many service departments would look at a 30 year old radio, especially as so many of them were 'doctored', often very badly, to do new tricks. Brian.
Hi there! I'm new to this site so please be merciful. Please have a look at the pic: 132199 I have two questions: 1 - Is this possible? (I assume that yes, but would like to hear from an experienced people) 2 - How small the Sensor Device can be? (most important questions) Thanks
First off hello all. Im new to trying to build a circuit board and have a question. I am trying to build a board to slowly fade on a 10w led flood light over about a 3 to 5 minute time frame using a 12v source. My question is, is this fesable and what type resistors and capacitors would i need. Thanks for any help. Zack
LWR, LER, boneheads, etc. look on articles in IEEE Trans. on Electron Devices and Electron Devices Letters, and Solid State Electronics from ScienceDirect. There are a lot of articles threating about new or more important effects in nano-processes.
i am new to this PCb design field, I have few doubts as i started working on High speed designs, 1. Routing DDR3 signals on top layer instead of inner layer which one is preferred, in my design it is on top and bottom layer. what is the advantage? 2. Address and clock on separated layer, data on other layer what i can do if there is no space to
Today bought a new development board, to share with you, it is very suitable for me to look at the board of the first board to see the board of the board based on Samsung's 6818 can run Android, Debian system

Sounds like either faulty diodes or a large voltage spike from some unknown source. What is the new brand/manufacturer of diode? Can you look at the diode voltage when the load is switched with a high speed (50MHz) oscilloscope?
Thanks BradtheRad But I don't want invest more time on new circuits I want to use Thread #7 or Thread #4 circuit for gate driver for 36 V to 24 V battery charging using buck converter As in both cases #4 gate drives are for 12 V only & I want to change it for 24 V
Can some one suggest some good and explained tutorial for PCB design in Proteus(VIDEO/PDF with Pictures) I am new to PCB design And Other reference Materials Like Guideline and Best Engineering Practices for PCB routing/ Track sizes ETC Thanks
Hi! I'm new using Altium.. I'm trying to make a PCB which can be connected to the chipkit uno32, the problem is when I try to bring near two pin headers, I can't... there is a white area around the components and I can't eliminated it. Here is an image with the problem, thanks!! 129823

Hello All, I am new to STM8AF MCU. I have configured TIM1 and TIM3 as PWM output channels. TIM2 channel 1 (PD4) as input channel. I am getting correct result when I look at PWMout result in CRO. Same PWM output of TIM1 channel1, I am feeding as input to TIM2 channel1(PD4) and sending over CAN. When I look at result in CAN it is throwing (...)
Thank you for posting clearer new schematics. I am also confused by the odd looking Mosfet symbols in the book and in Cadence. The Mosfets are shown to have a separate substrate pin so maybe they are IC Mosfets and are not manufactured Mosfets that we buy. They show the arrow on the source pin but datasheets and Google show arrows on the substra
This happened out of no where! I created a new file and added capacitors in the schematic view. Then I started tuning to look at the changes in the s parameter like I did in all my other designs. However, this time every time I move the capacitor value the setup solver starts simulating again and it takes waaay too long. pleaase help thank you
Hello everyone, I am very new to RTOS. I have basic knowledge about embedded programming. And I am given a task that i should use the SYS BIOS RTOS to run a simple example ( say LED BLINK) on msp430f5438 evm board. I am using CCS IDE for that. I have no idea how to start with. Can anybody help me out to solve my pbm.???? Thank you in advan
berrylium copper can look bent, but when you push on the bent bit, it will snap back to the bent position like a spring. bent brass will just stay in the new position you bend it to. beryllium copper looks just like copper to me, maybe just a little hint of a browner color. but it is usually plated, so you would not know.
Hi ! i'm kinda new to HFSS and wanted to know how to horizontally feed a microstrip patch antenna with a coax cable . i have seen the other threads using a coax too feed the ground plane but i have problem feeding it through a microstrip feedline . what percussion should i take or what boundaries conditions should i set . i include examples showing
Hi, I am new to 8051 microcontroller and have not done any professional course regarding this. I wanted to make obsatcle avoidance robot for may baby. So i wrote the programme.

Assalamualaikum, Hello all i'm new here I want to ask how to show farfield of 2 or more antennas on CST MWS in 1 file CST, I mean i create 2 antenna in 1 file and i want to look farfield of both in one time, i have been try but the farfield result was 2 farfield but in 1 position, i can't move one of them, so it's look like just 1 (...)
HI, Can we design a look-up table without targeting to FPGA , means using standard FETs in cadence. ? I am new to look up table and vhdl. thanks
Hi, I have designed a circulator in HFSS but I am not able to get good return loss and isolation.I have attached my file.I am new to HFSS, so I am not exactly sure whether my setup is correct .can u guys take a look and point out what is wrong in the setup. Thanks in advance Regards, Sai prudhvi
I am using PIC24F series and went through the project wizard. Is it possible to go back to the wizard and include some other functions. I find that wizard is only one time and we cannot revert back without creating new project. My second problem is running the compiled code from ccs in proteus. My code has look up table defined as A={1,2...
Hi, I have some experience with digital pll. However, I am completely new all digital pll. I am looking for a practical design book on all digital pll. Any recommendation?
The new version of Matlab R2014b contains some Simulink models demos that may help.
unless I was building 1000's of units I would not consider anything less than a PIC24 for new applications If you moved to a dsPIC33 you could use onboard ADC's with DMA, i.e. moving sampled data directly in memory using double buffering have a look at Microchip's product selector and
It is called multi part component in Altium. You need to create the component in proper way in library, where each symbol is drawn as Part under one Component. look at new Part command in schematic symbol editor. Then you need to have same Designator to all parts to get them all to one footprint. Petr
Hello, I want to thank you in advance for taking the time to help me. I am new to HFSS and I am trying to find a tutorial how to design and simulate Split ring resonators in HFSS. I don't know anything about excitation's or boundaries either. Can you please point me to some material I can read which can guide me as a beginner.
Here it is :) If you want a closer look you can go here:
I am new to VHDL so please help me There are two signals RESET and IN. How should the sensitivity list look like if a method should be called on a rising edge of IN and on every change of RESET? I know about the sensitivity list and I understood the change of RESET also but what mean RISING EDGE OF IN. Please help me to understand this Tha
Hi folks, I'm sure this question comes up a lot but it's hard to find a good comparison. I'm looking for a new free schematic/routing software. Having a large library parts database is nice, but I prefer to make my own parts, so really I'm more interested in what is easiest to make parts in. Simulation is nice, but I don't do much s
Hi guys, I am very new to this topic, so I would like to know what is the standard procedure for extracting the parameters of a compact model that describes the behaviour of a MOS-like devices? Supposing to have: -Few sample wafers with devices from a very new technology, with different L, W, W/L,... -The mathematical formulation of Id as
As I know there's no way to write the OSCCAL value in the mikroC source. Perhaps you can put it as a new line immediately in the hex file, before its last line. You need the address, the value, and have to calculate their checksum. Until then look at this sites: and
you have to select all parts in the navigation tree then choose in modeling tab export to sat but choose version between 18:20 it is near the name file. (because hfss work with version older then cst). or if you have the new version export to parasolid x_t. then you can import it in Hfss look for import under one of menu parts.
I'm trying to interface an SPI SRAM chip with a PIC18F4685 in Proteus. The data appears to be sent if I look at the SPI debugger, but right after that there is a receive with ?? and Proteus returns "Unrecognized command code ". Right now I'm only trying to write. I will later implement the read. I've attached an image of the SPI debugger. Yo
hi treez, Did you use 'Add Files to Project' or add 'Add new Files'.?? Use the 'Add Files to Project' look at this image, added two files to the Source folder. E
I have the old (2003) datasheet of the LM3914 from National Semiconductor. I did not look at the new datasheet from Texas Instruments who recently bought National Semiconductor. On page 21 they show the "new" DIL case for the LM3914N1 and on page 22 they show the old LM3914N DIL case that was not available after 1999.
