hi ng, i get the following error-message during "Programming File Generation":



ERROR:Bitgen:145 - Pin M6 is a persistent pin, but a component exists in it's IOB. Please rerun par with the persistent pins prohibited from use. ERROR:Bitgen:157 - Bitgen will terminate because of the above errors. Error: bitgen failed Reason: Process "Programming File Generation Report" did not complete.



Here is the evil code fragment:



pIR : process (CLK, Reset) begin if Reset = '0' then Pending
