FPGA Express: out of virtual memory error. synopsys internal error 217
Description
Keywords: FPGA Express, 2.1.3, winNT, out of virtual memory, synopsys internal error, 217, hang, crash, core dump, optimization
Urgency: Normal
General Description: Compiling certain designs through FPGA Express may result in the following error after being stuck during the Optimization stage on "implementing inferred operators"
out of virtual memory error. synopsys internal error: 217
Solution
In the modules tab of constraints editor, set Operator Sharing OFF on the top level design. Also, it is recommended to use AREA/LOW_effort option for faster CPU time.
Increase the amount of physical and virtual memory if possible.
Be sure to use the latest version of FPGA Express, as issues like these are addressed with each new release.
