Problem Title:
M1.4 CPLD: A fitter crash may result from properties applied to wrong objects
Problem Description:
Urgency: standard
General Description:
The CPLD fitter may crash due to design properties being assigned
to the wrong type of objects.
Solution 1:
If the CPLD fitter program hitop crashes, check to see if there is
any I/O buffer, pad or pad-net in your design that has a property
attached to it that is intended only for macrocell-type objects.
The macrocell-only type properties are COLLAPSE, INIT, KEEP,
NOREDUCE, PWR_MODE and WIREAND. Using any of these properties on
an I/O object should normally produce an error or warning message.
Remove any such properties from the I/O objects and attach them to
the applicable macrocell objects (logic or flip-flop components),
and rerun the fitter.
