How forcing assura QRC to keep analogLib device from schematic to extracted view ?

 Hello,

I try to build a simulation flow to improve top simulation of our design with assura QRC  extracted RC view.

Currently in schematic view we have some analogLib devices to help DC convergence, such as sp1tswitch, bsource or vdc for example.

Those devices have of course the property lvsIgnore=TRUE for LVS compatibility.

The problem is that such devices are not reported in assura QRC extracted view also.

Today we add manually convergence  devices in .scs netlist before simulation, but this is not really helpful with simulation flow using ADE, and we sometime forget to update convergence device when new extracted view is built.

 

I did try the solution to add such device in the extracted view by using some skill, but I did not succeed. This method need better skill knowledge and time that I do not have.

Is it possible to program assura QRC in order to report such analogLib device directly in the extracted view ? (and keep the property lvsIgnore=TRUE of course)

 

Thanks in advance

 

Olivier

    Hi Olivier

    That was a really good description of the problem. Thank you. : )  Providing the tool versions definitely helps a lot in understanding and solving the problem.

    Best regards
