Need help in understanding the simulation directory!!!!

[Samiran]

Hi all,

Suppose I have a cell with name "samiran_test" for which a directory
has been created inside "Simulation" directory. There is one file in
the path: "Simulation/samiran_test/spectre/schematic/netlist/amap/
samiran_test.f.inst" whose content is as follows:

HEADER
"PSFversion" "1.00"
"C0v" "C0"
"C0n" "analogLib_cap_spectre"
"V1v" "V1"
"V1n" "analogLib_vsin_spectre"
"R3v" "R3"
"R3n" "analogLib_res_spectre"
"R11v" "R11"
"R11n" "analogLib_res_spectre"
"R5v" "R5"
"R5n" "analogLib_res_spectre"
"G5v" "G5"
"G5n" "analogLib_vccs_spectre"
"G2v" "G2"
"G2n" "analogLib_vccs_spectre"

Could anybody please explain what do the "v" and "n" mean as they sit
after the instance names e.g. "C0v" and "C0n"????

Thanks in advance!

Cheers
Samiran

Samiran,

The format of these mapping files is private, undocumented, and liable to change
in any release. So you should not use it for any of your applications. They are
used by various of the netlisters to keep track of mapping between schematic and
simulator names.

Andrew.
