others clause is not synthesized
Hi all guys:
I want ro generate a safe state machine, When the machine enter an unexpected state or an unreachable state, it can recove from these error state and run continuely. I have created a finite state machine by VHDL, synthesized by synplify with the atrribute "safe", however, the log warns that "OTHERS clause is not synthesized", and the synthesed result is tha same as the one sythsized without the attribute "safe". Whenever I add the attribute "safe" in the *.sdc file or directly in the VHDL source file, syplify shows the warning mentioned above. I refer **broken link removed** as my guide, but get this result.
what is wrong? how can I get a safe state machine synthesized by synplify?
Best regard.
