Get*Error*PasCdfCommitValue while Refreshing CDF using abConvertComponentParams.il

George Qin

Dear Andrew:

I want to refresh CDF of PDK cells of all schematic in my Library.

Environment: Virtuoso 6.1.6-64b

seems that CDF parameter was sucessfully refreshed(at least the value displayed on schematic is corrected by this script).

And the function also feedback "t" at end.

But why there appears following Error message while refreshing some of blocks?

*Error* PasCdfCommitValue: failed to find valid initialization data!

*Error* PasCdfRevertValue: failed to find valid initialization data!

My step:

1. load skill file in CIW:

load(“/../../abConvertComponentParams.il”)

load(“/../../abInvokeCdfCallbacks.il”)

2. Use the following function in CIW:

abConvertComponentParamsForLib("xxxx(my Library name) "schematic" "../../conv.config")

My conv.config file:

But I get the Error message shown below:

    For PDKs created with PAS (PDK Automation System), you typically need to specify some additional arguments to be passed to abInvokeCdfCallbacks, so change the runCallbacks t to: 

    runCallbacks (?useInstCDF t ?callInitProc t)

    (it might not need the ?useInstCDF t but I think it probably will...). The ?callInitProc is the specific part needed to solve the PasCdfCommitValue error.

    Regards,

    Andrew.
