I would put a trivial series resistor between any veriloga block pin, and the larger schematic. Any parallel "stuff" should be attached to the outboard ends. In my experience this forces the conversion of port I, V to be done in a way that works for SPICE / Spectre. And it lets you probe a well behaved, no-mystery primitive element which is hard (
Hello all, I imported a verilog netlist for a layout previously designed in Encounter. When I try to open the schematic and hit check&save, I get these errors: Error: Net "v_CALCULATION_CNTR<7:0>" shorted to net "N5512,N5511,N5510,N5509,N5508,N5507,N5506,SYNOPSYS_UNCONNECTED__0". Error: (DB-270004): Illegal bus reference - Can't tap "
Hi, in this schematic a sub-harmonic polyakov mixer is used together with a saturable reactor to form a simple (lossy) direct conversion receiver. I read the description, but I need a bit of help about how to wind the cores and why do they have to be of opposite phase in the OSC side?
Dear All, Can any body help on schematic conversion from Dx Designer to Orcad. Thanks in advance. Regards Amarnadh
Show me schematic.
ADS will create a symbol view with ports how many there are.. If you don't want to use them all, keep them unconnected on the top level schematic. Or, delete the ports which you don't desire to see in sub-schematic.
Hi, I am trying to measure 50Hz AC RMS voltage using PIC18F4520 microcontroller. schematic shows how I am giving the input to ADC. adding a DC offset of 2.5 to the transformer output. there is also a zero crossing detector to take the samples for just one complete cycle correctly. But the measured values are not constant. so I measured 50 cycles
hi i am doing the design of CMOS stage Cross couple rectifier with high efficiency performance. but i have a few question for my schematic stage. i design using galaxy custom designer by synopsis 1) how to calculate the power conversion efficiency of the rectifier using the SAE tool? 2) Is it possible to do dc biasing for my circuit, as through
I think you should show a schematic to clarify about your darlington and level conversion problem. Generally, IR2110 can be driven by 3.3V logic signals without additional level conversion. VDD should be connected to 3.3V logic supply in this case. 3.3V logic with 5V VDD will "typically work", but not guaranteed by Vih datasheet (...)
Hi all I have chosen the AL210 for this Ethernet to Fiber optic conversion.I have doubts and I have posted my schematic and its datasheet.Can you tell me what things i have done wrong in the schematic. 1.Pin num 20 & 27..I don t know how to give connections.and i don t know what is the meaning of Reduntant data sheet They have split
It's also not completely clear what "differential current" means for you and how it will be sensed, can be e.g. dual ground refernced current sink, truely floating differential current sink, etc. But a schematic including the current source should clarify.
No schematics can be converted directly to HDL code.
The super-regenerative receiver can receive FM also: On your schematic, perhaps will be very hard to find the old Russian GT311 "hat" transistors. Have to search the surplus market for some old out-of-use satellites or tanks :-)
Has anybody ever worked on usb to sata conversion using GL830 or any other IC. I have designed using GL830 but there seems to be an issue. Can anybody help me? i will share the schematic.
erikl - you are right, one needs to have a rule file corresponding to this GDS file and to this technology. The most important things that rule file will provide are: 1. connectivity - which metal layer is connected to which other metal layer by which via layer 2. device recognition - so that the software understands where the devices are formed,
Can you attach the schematic again Alek, for some reason the link is not working. I think we need to see a schematic to answer your problem, from what you describe you did everything correctly and the two grounds are the problem. It may take some miinor redesigning to bring the real and virtual grounds together. Brian.
Your schematic drawing software creates a nightmare of wires all over the place! Also the grid lines are distracting. You do not show an input frequency range. Your 5V power supply is much less than the 15V shown in the datasheet.
Hi, a schematic could help to understand your problem. ****** A passive CT only works with AC. DC is not possible. AC means alternating current. Alteranting means it changes. Often AC is sinusoidal. If you do an AD conversion on a sinsoidal voltage you may get results ranging from negative peak to positive peak voltage. For example: doing c
please, can you help me? I need create design of power supply for GSM module SIM900. I found some catalog schematic of LM2576 ADJ as STEP DOWN from 12VDC to 4VDC. It's ok, but I need step down converter from 24V AC. Is good idea to use catalog circuit with diode bridge in input? Which solution do you suggest? Diode bridge or simply use of on

Also, Using altium tried saving the project to .dsn format, but doesn't work I get the following error: """"" ********************************************************************************
Hi All, I converted a orcad capture(.DSN) schematic file to altium designer schematic. During conversion properities attached to schematic symbol getting removed. Pls let me know what is the exact procedure for conversion. Thanks, shabby.
I have a design in Orcad capture. I want to convert it to Candece DFII format that can be open in Virtuoso schematic. How to do the conversion?
Post your total schematic. Then only We find a what is the problem ..
Hi Friends. I want to open PADS schematic file in to dx-designer. can anybody tell how to do this? THANKS
Some comments: Have you completed a standalone Momentum simulation on the antenna network yet? This would show that the EM simulation was set-up correctly before attempting the co-simulation in the schematic. It looks like the wire connecting from C1/C4/C5 and the antenna has a red indication on the antenna end. This indicates that it is not
Check on oscilloscope what are you getting from pin A or B. In your schematic it'll be better to use pull up and pull down at A & Bwhile using 485 conversion... wikipage of RS485 has details explanation about how to connect them and why we need them and which values we should use for pull up & pull down. Because it seems that your slave may not be
Hi, SAW filter is for : Surface Accoustics Waves. I think that you can't create a layout of this type of filter in ADS except a simulation of the schematic that modelize this filter. SAW filters have a special substrate where accoustic wave travel. The transducers assume the conversion between electric HF signal and accoustic vibration signal. In
Hi i am using orcad 9.1, i wanna ask is it possible to develop schematic from layout?
No details of the file extension of the schematic was mentioned. A schematic on a paper, JPG, BMP or PDF format can only be converted to a PCB layout by Human brain on a separate software meant for it. In case you have the schematic in .sch, or any such designing software format, it can be converted to PCB by the same software.
I need your full schematic from Analog driver , ADC analog/digital ground isolation, DAC output. It is clear your noise is independent of the signal input frequency but dependent of sampling clock rate lower than 250MHz. To me this is analog noise that can come from multiple sources which I can only guess without a schematic. 1. Commutation nois

Hello, Attached is a schematic that now only resembles the UHF receiver I have been designing. It simulates fine but when placed on a board it required alot of modifications to get working. Anyway I can inject a signal at the Antennae port at -100dbm and view the signal on the spectrum analyzer after the saw filter at -90dbm. The oscillator wor
