Pspice v17.2 Crashing and Convergence Problems

I updated to Pspice v17.2-S022 when it was released earlier this year. When I first used this version to perform an AC frequency sweep analysis of a simple op amp transimpedance amplifier, I found that it either tended to crash with messages like "orSimSetup64-this application has quit" or "INFO(OrProbe-3211): simulation error, the rpc server in unavailable" or tended to fail to converge on nearly every run. So I uninstalled this version and re-installed an earlier version - v17.2-S015 instead. I found that this version tended to work properly on the initial simulation run but would tend to crash on a subsequent simulation run after making circuit component (resistor and capacitor) value changes. My original circuit used a Texas Instruments OPA140 op amp (macromodel supplied by Texas Instruments). Thinking the problems might be related to this op amp, I replaced it with a LM258 op amp from the Pspice standard library and got the same problems. I contacted my VAR for help on this. They ran their own simulations on my circuit and did experience convergence problems but not crashing problems and they are at a loss to tell me how to resolve either problem. Has anyone else experienced crashing and/or convergence problems with v17.2??

As someone who has used Pspice v16.6 for several years, I have the impression that while v17.2 has more features than v16.6, it is less stable/more problematic than v16.6. Does anyone else have a similar impression??

Thank You Frankfar - Please request you VAR to report this case to Cadence support. It is difficult to comment about such issue without having a specific look at the actual design. Cadence will address issues if any.

It seems that you are facing some issues with PSpice v17.2-S022 while performing an AC

Snow Rider 3D frequency sweep analysis of a simple op-amp trans-impedance amplifier. The error messages you mentioned indicate that there might be a loop involving the voltage source and/or inductor in your circuit. This error can be resolved by adding a series resistance to break the loop.

I'm sorry to hear about the issues you've been 

cut the rope experiencing with PSpice v17.2. It seems like you have already taken some troubleshooting steps, such as reinstalling an earlier version and trying a different op amp model, but the problems persist.

While I don't have real-time information about the specific stability or convergence issues with PSpice v17.2, it's not uncommon for software updates to introduce new bugs or compatibility issues. However, it's also possible that the issues you're encountering are specific to your system or configuration.

In situations like this, it can be helpful to seek assistance from the software's support channels. Since you mentioned contacting your Value Added Reseller (VAR), they might be the best resource to provide specific guidance and solutions for the crashing and convergence problems you're facing. They can potentially escalate the issue to the software vendor for further investigation or provide insights based on their experience with the software.

It might be worth reaching out to the software's support team for further assistance, as they may have specific recommendations or updates to address these issues. By the way, have you tried playing Monkey Mart? It's a fun game that offers a unique shopping experience with plenty of challenges to enjoy.

 Your troubleshooting efforts thus far seem to have included reinstalling an earlier version. If you need more help, you should probably contact the software's support team to see if they have any suggestions or upgrades available to fix these problems amanda the adventurer
