The second line was type myTypeMatrix array( numberofitems - 1 downto 0 ) myTypeVector
I always try to strip irrelevant part of the code. Also when we post on the mailining list, the code may not compile if not all the code is sent. The issue was : does a cast should copy the signal into a temporary signal and then no update is done backwards ( it is what happened ) Regards _______________________________________________ Ghdl-discuss mailing list [email protected] https://mail.gna.org/listinfo/ghdl-discuss
