I have a warning. ../../../src/ieee/numeric_std-body.v93:1710:7:@0ms:(assertion warning): NUMERIC_STD."=": metavalue detected, returning FALSE ./jpeg_tb:info: simulation stopped by --stop-time
This is correct at time 0 it is not possible the asignment. The signal is not valid at time 0 but later. If I lock at the waves in gtkwave erverytime it is undefined. Ok it is my programming style. Typical I have a process which is stimulate by a clk and second I use the when statement outside the process. This is very practical for an address decoder or write enable. process(clk) begin if clk'event and clk='1' then State _machine--- end if; end process; data<="1111" when state=ready else"ZZZZ"; --this is not actualised by ghdl Rene _______________________________________________ Ghdl-discuss mailing list Ghdl-discuss@gna.org https://mail.gna.org/listinfo/ghdl-discuss
