F1.5,2.1i security: When does FPGA Express check out a floating license?
Problem Description:
Urgency: standard
General Description: Users may find that there are no FPGA-Express licenses available to check out,
even though no one is actually doing synthesis. This applies ONLY to users that are using floating
licenses. Node-locked licenses should not have any trouble.
Solution 1:
Express licenses are checked out when:
If you open up a top-level hdl project, the following licenses are checked out:
fpga-express
fpga-express-constraints-mgr
When you go to synthesize another license is checked out:
fpga-express-XXXX-optimizer (enter you target familt for XXXX)
When synthesis is completed, the otimizer license is checked back in.
If you open a top-level schematic project, NO license is checked out.
A license is only checked out during synthesis (create/update macro).
At that time all 3 licenses are checked out:
fpga-express
fpga-express-constraints-mgr
fpga-express-XXXX-optimizer
At the end of synthesis all 3 are imediately checked back in.
So in summary, if you open a top-level HDL project, you are 'reserving' a license that only you can
use for synthesis. Users should close their top-level HDL project when not in use.
