The exported map file from Encounter is wrong, so how to modify it to be able to get the correct layers in Virtuoso ? Here is streamOut.map file from Encounter: metal1 net 1 0 metal1 SPnet 2 0 metal1 PIN 3 0 metal1 LEFPIN 4 0 metal1 FILL 5 0 metal1 FILLOPC 6 0 metal1 via 7 0 metal1 viaFILL 8 (...)
I don't find a lot of use in describing a clock net as global / local. Most non-trivial designs will tend to have more then one clock domain. And they should all be considered GLOBAL. Bifurcation of clocks inside an FPGA should only be done via a dedicated component that has access to dedicated clock routes (PLL / DCM / MMCA / etc...) All (...)
Hello every one I don't understand about how the mikroc send data via serial port. I have made application by using but couldn't send data like MikroC application, it gives me error, please help!
Hello everyone, I have a cell balancing circuit for li-ion batteries. I want to use voltages or current that be able to measure via current probe, in the equation. It can be used in MeasEqn but not in the VAR. If you help me, I am glad. - - - Updated - - - Even I did what you said, it could not work. Fo
Hello Guys, I have made a software for debugging via serial port. It is freeware. Please do download and use it from the below link. serialterminalutility.sourceforge.net For updates you can visit www.ajishgopalr.blogspot.com T
Can anyone help in calculating the total resistance of a net from DRM 90 nm? I know the formula : R=Rsh*L/W i have added all the via resistances also associated with it. But still my total resistance is little less from the actual total resistance (i got this total resistance from spice netlist after extarction, i just
Can you manually route on the copper then add a via?
hi every body im trying to send some datas via post method in http from my sim900 module to a web page in a web server my web page is working good & i can post datas to it via browser in my pc and html forms but sudenly i cant send datas from my sim900a module can receive datas
hi, delete the ground shape or copper area as well as vias. Now try it below method. choose icon shape--->polygon or rectangle then select the net as ground now draw the shape in your require area after complete.place via in copper area location
Hi All, I am trying to turn on an LED via pmod. but it is not working. i am using nexys3 board. Here is verilog code: module TestWheelDriver( output ain1, ain2 ); assign ain1 = 1'b1; assign ain2 = 1'b0; endmodule Here is the part of ucf file where i change pin connection on JA. ##JA net "ain1" LOC
How to find/remove the unwanted traces (Dangling lines) & vias in Altium? Thanks.
Old thread, I know, but for future reference - while you have hold of the floating via with the cursor, hit TAB to get the properties. Go to the net drop down and choose the net that you are going to drop the via onto. That via is now electrically connected to the correct net. I believe the (...)

As far as I know, PHP has its own capabilities for creating graphs so you can do everything you need just with PHP. Also, as far as I know, VB is not compatible with PHP, so you can't include VB code and PHP code in the same page. However, you should be able to pass variables to a web page via any programming method you want (using POST or GET). Yo
pls do the following: 1. Check whether auto update DRC option is enabled or not... 2.check the same net rule if you routing same net on the database check once 4.check the via definitions once gain..
Hi everyone, I am using Cadence PCB Editor 16.3 to develop a board (4 layers). I have 3 vias connected to the GND_RF net. The Top Layer and Inner2 Layer have a plane connected to GND_RF. The Inner 3 Layer has a solid fill shape connected to the VCC nets (VCC1 and VCC2). The bottom has same nets connected to the GND_RF (...)

To refer to the problem mentioned in the original post, I agree that via opening should be separated from the pad copper by solder resist for regular vias. The most simple solution is a modified via padstack, with a smaller solder resist opening, e.g. 0.8 mm in the said case. The "acid trap" problem mentioned by Mattylad remains. Another (...)
Hello, I am currently into softphone development. While I was doing a little research came across a sample program that is in Visual ( ). This is a sample program that represents the development procedure via code snippets. It provided useful information for me and thought other

When you insert additional (double) via, it will change RC values of this net. If you don't want to change timing of the path through this net (for example, it may has negative slack), you should use timing_driven double via insertion - it will skip the timing critical nets for double vias. (...)
To your point 1 you need to design the via to the same characteristic impedance as the traces, so it doesn't look like a discontinuity. free simulation that might interest you
you could use TCP or UDP to send the patient data to a TCP/UDP server which could then be viewed via a secure web page
I would taper the lines at the switch, to reduce the discontinuity. This will also give room to place the ground via near the
Hi all I have designed a temperature monitoring device that connect to my computer via serial port.I have tested it and the readings are successfully shown on a small vb program i this everything gone OK!. Now i want to display this readings on another computer(of course on a vb program) on problem is how i can send th
You can make direct contact for all vias you will not have any issue with that. But via clearence is very low make sure you fabrication house can provide you that clearence. You can reduce the width of your copper poured between the BGA via and increase the clearence.(like if it is 0.2mm you can make it as 0.127mm).

Hi there! I placed a via and connected it to ground by renaming it. Now I am not able to remove it, Eagle just tells me to do this in schematic (thinks I am trying to remove all ground connections), but the via is of course not in the schematic. Any sollutions to this? Thank you in advance!
This is a project of simple boards, ready to be connected via ribbon cables. It is a good alternative for pin plate, because mounting the multiplex display or matrix keypad, though simple, is very time consuming. With this device,
I too would be looking at poor grounding, poor sheilding of sensitive signals so your getting crosstalk, faulty via, even an incomplete net/bit of ground not actually connected to the rest of the gnd net. Temporarily fixed by you adding yourself to ground that area perhaps?
As Kabaleevisu wrote these might be via assigned to pad during footprint creation. These vias take net alias of the pad they are placed. As you can see in blue coloured pads all vias are covered with the shape as they have same net but only yellow coloured pads and vias have isolation (...)

Hello, You constructed your prototyping area with via you copied from your design. However, when you did this you also copied the via signal name (GND). When you want to copy a via without its net name, you have to (un)check the "copy net name" (or something like this, I don't have allegro in front of my (...)
