are the schematic <-> spectre names mapping valid when a netlist of a subckt is attached to the test bench

Hi, 

After creating the maestro testbench netlist using the "maeCreateNetlistForCorner" command, I am using a post processing script to replace some subckts of given subblocks (for example subckt of blockA is replaced with a modified subckt of that block) in the netlist, followed by running the simulations, now as the contents of this sub-block (instances and their respective subckt names and definitions) has changed, would this invalidate the "amap" data ? how to ensure that when opening the results, the evaluation of the schematic names would be still correct, or what would need to be modified in the amap data, 

I would also appreciate some extra information or a pointer to documentation on how spectre to schematic name mapping is done while evaluating the results expression and how can to ensure this is correct if the simulations are done from through a spectre cmdline 

"virtuoso version ICADVM20.1-64b "
"sub-version ICADVM20.1-64b.CUSTISR33.24 "

Thanks, 

Fahmy
