Hi, When I run ams simulator Following error occurs:
E,SPCERR (No source,0|0): The program encountered one or more errors while processing the input SPICE file(s) in the AMSD flow. For details, see the following messages.------Irun found errors(s) during the processing of SPICE files in AMSD flow.These could be fatal simulation front-end (SFE) parsing messages or errors found during AMS SPICE processing. Correct these errors and re-run simulation since they will effect the AMS simulation results.
What should I do?
Hi ArslanThis might be the same problem explained in COS article 11808980. You should be able to resolve it by shortening the model path or by upgrading INCISIVE package to any version higher than 11.1.s057.Best regardsQuek
In reply to Quek:
I am encountering this same error and there is no descriptive error message available. I tried copying the model files to a shorter path location, but that didn't work. The tool reports that it is using: irun: 13.20-s006, and the only error message is:
irun: *E,SPCERR: The program encountered one or more errors while processing the input SPICE file(s) in the AMSD flow. For details, see the following messages.
amsspice: *Error: terminated with error code 2
In reply to swirhun:
Hi PaulAs there are no specific error messages, I think maybe we can start from basic system checking. Would you please post the output of the following cmd?terminal>$INCISIVHOME/tools/bin/checkSysConf INCISIV13.2Best regardsQuek
Thanks for the quick reply. Maybe not surprisingly, the command you said to try gives a "Fail" output...
[This post has been updated. If the tool fails to run and display PASS/FAIL reports, then it is running from the wrong location. Use the full path as Quek explains in his response].
Thanks for the help,
Hi PaulWould you please substitute "abc" with your actual path?terminal>/abc/tools/bin/checkSysConf INCISIV13.2You can get the path to ncsim using:terminal>which ncsimBest regardsQuek
It looks like the configuration checker reports that we are using an outdated ksh library. I will ask our sysadmins to update it and report back tomorrow.
UPDATE: I'm writing my solution here so future frustrated people can try to find a solution more quickly.
Although there are errors in the configuration-checker report, I was able to get AMS simulation working by checking the box "Run with 64 bit binary" in ADEL -> Setup -> Environment. Nothing new was installed.
A rudimentary testbench now appears to be working! Gate models and their containing folder are specified in ADEL -> Simulation -> Options -> AMS Simualtor -> "Library files" and "Library directories".
Make sure the config stop list includes "verilog", I have mine set as "spectre verilog" and the view list is "spectre spice verilog verilogams behavioral functional systemverilog schematic veriloga vhdl vhdlams wreal", which I believe is the default if you load the AMS template.
Hi PaulThank you very much for the update. We really appreciate it very much.Best regardsQuek
