M1.4 TRACE: Do NOT activate CMOS level timing for XL family


Urgency: Hot

General Description:

The speed files for the XC4000XL family do not have data

for CMOS level outputs. If you activate this and run timing

on the design, the output delay values will be incorrect.


The XL family does not support CMOS level outputs, so

this option should not be activated in any case.
