ISE MAP problem

when I use ISE 13.2 to synthesize V6-240T project, if I select map global_opt option to speed, the ISE tools will halt at MAP stage, the tools runs global_opt speed optimize for long time and tools won't acess next map stage, it is hang there.

other problem is DDR3 controller, when we select global_opt for speed, it will report following error at place & route stage. and we try add "S" for these signal in UCF, it is still reporting these error.

if we disable global_opt, two oroblem will disappeared, but STA wil report timing issue.

 

5 signals are not completely routed.

Re: ISE MAP problem

There are few knwon issues reported while using Global_opt. It will be obsolete from GenX tools.

 

I recommend you to not use the global_opt option.
