Why is my siwave_ng syz simulation execution taking too long?

jcjustinchoo

I'm encountering an issue with the execution of syz simulation using siwave_ng, and I'm hoping to get some insights or suggestions to troubleshoot this issue.

Setup Overview:

I have two scripts to automate my simulation tasks: autosim.py and main.py.

autosim.py:

• An IronPython script designed to configure the Siwave UI for my syz simulation.
• It handles tasks such as creating ports and resistors, activating necessary capacitors, and managing the configuration for the syz simulation.
• The script appends sweeps, sets syzInterpSweep to True, and saves the Siwave file with the relevant ports and resistors activated for the simulation.

main.py:

• Utilizes Python 3's subprocess module to run Siwave UI with autosim.py and siwave_ng for syz simulation.

• Runs Siwave with the command line:
  <path_to_siwave.exe> -RunScriptAndExit <path_to_autosim.py>

• After autosim.py completes, it initiates Siwave in non-graphical batch mode to execute the syz simulation with:
  <path_to_siwave_ng.exe> -formatOuput -l

Execution Details:

The execution file contains the following commands:

ExecSyzSim
NetsToSimulate ".*"
SetSIwaveSyzSimName AC Sim
ExportTouchstone ""
SaveSiw ""

Problem:

The process is getting stuck at "processing traces..."

Request for Help:

I'm looking for suggestions or troubleshooting tips to address this issue. Any advice or similar experiences would be greatly appreciated.

There's a typo for the command lines:

For siwave UI with autosim.py: <path_to_siwave.exe> -RunScriptAndExit <path_to_autosim.py>

For siwave_ng: <path_to_siwave_ng.exe> -formatOuput -l

There's a typo for the command lines:

For siwave_UI with autosim.py: "path_to_siwave.exe" "path_to_.siw" -RunScriptAndExit "path_to_autosim.py"

For siwave_ng: "path_to_siwave_ng" "path_to_.siw" -formatOutput -l "path_to_log"
