M1.3/M1.4 CPLD Hitop - Hitop hangs for 9500 design
Description
Keywork: hitop, hang
Urgency: standard
General Description: When implementing the design through it hangs during the following command: hitop -f ../xc9500.ngd -d design -s -l design.log -o design
Solution
Resolution:
For M1.3 - There is no resolution other than upgrading to M1.4
For M1.4 - Turn on the switch for Multi-Level Logic Optimization in the Implementation Option Template (this is usually on by default)
NOTE: This is fixed in M1.5, where you don't need to turn on MULTI_LEVEL_LOGIC_OPT to get hitop to complete, but you will still need it to get it to fit.
