Problem Title:
M1.4 TRACE: Do NOT activate CMOS level timing for XL family
Problem Description:
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.
Solution 1:
The XL family does not support CMOS level outputs, so
this option should not be activated in any case.
