I can think of 2 ways: You can use $value$plusargs at run time to get the path you want to use at run time as an extended argument to the vvp command. This won't work for synthesis, though. You can replace your text with a macro, and define that macro in your Makefile (-D) or your iverilog commands file (+define+). This will work with synthesis because you can also pass the correct definition of the path to your synthesizer command line. > In rtl/ and tb/ I have my RTL implementation and in tb/ the test > benches.

Re: gEDA-user: Icarus Verilog: specify path for $readmemh?
Hi, You could try using a relative path, that is: Replace "Romfile.txt" with "../sim/Romfile.txt" This might get you past the problem, at the expense of forcing the directory structure to always have the file in the 'sim' directory. I think the Xilinx tools can deal with the slashes. -Original Message- From: Günter Dannoritzer <[EMAIL PROTECTED]> Date: Fri, 21 Mar 2008 12:40:43 To:gEDA user mailing list Subject: gEDA-user: Icarus Verilog: specify path for $readmemh?

gEDA-user: Icarus Verilog: specify path for $readmemh?
Hi, I am using the system task $readmemh to init some ROM. Now my question is, can I specify for the simulation with Icarus somewhere the path to the file I am using with $readmemh? Here is my dilemma. My folder structure is as follows: + rtl/ + tb/ + sim/ + syn/ In rtl/ and tb/ I have my RTL implementation and in tb/ the test benches. In the sim/ folder I have a Makefile that does the compilation and simulation with Icarus Verilog. Now the $readmemh call is in some code in the rtl/ folder. The way I solved the path issue is that I moved the file that is read with the $readmemh call in the sim/ folder. Now the conflict happens with synthesis. In the syn/ folder I have a Makefile that calls synthesis with Xilinx webpack/ISE. It expects the file that is read in with the $readmemh call is in the rtl/ folder. I guess I could copy the ROM file in both locations or specify some macros and have two different $readmemh calls. Anyhow, is there a way to tell Icarus that the ROM file to be read with $readmemh is in another location than the folder the simulator (compiler) is called from? I did not find a command line switch that would apply to that issue. Thanks for the help.

The most correct thing to do is edit the BNC connector symbol (select it, then do hierarchy -> down symbol), and move the pin onto your grid. You can modify the grid and snap settings using the "options" menu. > or how can I connect without using the snap? You're better off just doing the right thing: fix your symbol.

Remove the symbol and readd it while snap to the grid is enabled. There are some possible reasons why the symbol is not on grid: * you've added or moved the symbol without grid enabled * you're using gEDA version between 20070216 and 1.2.0 which has a Edit->Mirror bug Regards Werner ___ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
