I don't know the answer to your question but the
following MIGHT lead to a solution. Essentially,
if you use STL to specify the circuit stimulus and
perform a simdiff, the resulting si.log file will
output lines like:
*Mismatch* out at time 9.9e-08 - expected (voh) simulated (2048)
There is a line in my STL source that reads
; specify voltage windows to define a input/outputs highs and lows
deflevel cmos vil=0.0 vih=5.0 vol=0.0 voh=5.0
I haven't pursued this but with some magic, you
might be able to get a table of voh/vol's.
