Big Problems with bidir Pin :-)

Hello,

thank you for your reply.

It's a good explanation for the added variable.

So, I made a new vwf-file to test this, besides I erased the clock, because I don't net it.

The new project: http://rapidshare.com/files/33104146/iobuff_test.zip.html (http://rapidshare.com/files/33104146/iobuff_test.zip.html)

The VHDL Code works this way, that if oe='0' the value I set to "io" is shown on the output.

But then I want the value on input to be shown on io~result. I set oe='1' and the value on "io" to "DC" (Don't Care).

On the simulation you see, that the value an io~result (which should be the same linke "in") is unknown.

I have no idea why this value is unknown. It should work like described in the VHDL Code.

It makes no sense to give "io" another value for the time oe='1' because this value will be the same like on io~result.

Best regards,

Christian
