At the beginning of a PEX run for a new cell in Calibre Interactive, I see a message that my PDB from a previous run (for an unrelated cell) is deleted.
Verifying the source netlist is complete before starting the run
Deleting PHDB CELL_B.phdb
Deleting XDB CELL_B.xdb
Deleting PDB CELL_A.pdb
Deleting template directory
I am running PEX on CELL_B, so it makes sense that the phdb and xdb for this cell are deleted. But why does it delete the pdb for CELL_A? Is there a setting to disable this? My workaround is currently to set a new run or svdb directory for each cell so that I can go back and look at previous parasitics. But there must be a better way...
Thanks in advance,
By default, the PDB is re-created every time CI runs the PDB step. There's a box, "Generate PDB Incrementally" in the CI-PEX Outputs > SVDB tab. Select that, and the PDB should stick around.
