I am developing some kind of state machine, probably I will use EPM7032 but maybe some project specyfication will change and I want to know how many "free space" left in this chip (counted in % or free macrocells).
BTW is there any possibility to look how compiler made its work at gates level? (like in Synplify)
Check in report file. There is an icon 'RPT' you can click in the complile window. It is also accessible in the 'hiearchy view'. If you don't find it, just open your <project>.rpt file in the project directory.
You'll find everything including the megacell usage, free resources, routing congestion and even the equations. For a 32 macrocell project, the equations are not too complicated to follow.
