if return large data. skillbridge will throw exception. I'm use cadence 17.2, Allegro Package Designer L. input code:

comps = ws['axlDBGetDesign']().components
dir(comps[0])

output:

I'm using pycharm. when I click right comps->[1]. It's show the error message the mcm is SPB_17.4\share\pcb\toolbox\getting_started\panelization\mcm_context\databases\sample.mcm

Thank you for the additional information.

We mainly use the skillbridge for Virtuoso so it will take us a while to set up an Allegro environment.

Sorry for the delay.

Could you paste the whole error message here, please? The screenshot only shows a part of it.

Hi, i got the chance to debug the windows-channel implementation. Unfortunately i could not reproduce your problem. How big is the data you are sending?

Did you try to cancel a running skillbridge session with Ctrl+C? That can confuse the synchronization between client and server. The error you are getting looks like that.

when I'm use ipython, it's work fine. Use pycharm It's work wrong. I can provide my computer to help you debug. I'm try to solve. It's maybe wrong with Multithreading(pycharm debug).

Good hint, i will try it out in PyCharm and its debugger when i get a chance
