#1853 All multi-corner SDFs have the Slowest library operating conditions Issue created by passant5 Description Multi-corner SDFs are generated correctly (delays are different across corners), however, the operating conditions header states the Slowest library operating conditions for all corners. Looking at the operating conditions of the

spm

example generated SDFs at nominal typical and fastest, they have the same operating conditions as the slowest.

sdf/multicorner/nom/spm.Typical.sdf:
 (VENDOR "Parallax")
 (PROGRAM "STA")
 (VERSION "2.4.0")
 (DIVIDER .)
 (VOLTAGE 1.600::1.600)
 (PROCESS "1.000::1.000")
 (TEMPERATURE 100.000::100.000)
 
sdf/multicorner/nom/spm.Fastest.sdf:
 (VENDOR "Parallax")
 (PROGRAM "STA")
 (VERSION "2.4.0")
 (DIVIDER .)
 (VOLTAGE 1.600::1.600)
 (PROCESS "1.000::1.000")
 (TEMPERATURE 100.000::100.000)

Expected Behavior Multi-corner SDFs operating conditions should be different based on the process corner Environment report
