Is any problem with User Component Editor

Altera_Forum · ‎05-13-2005

My develop kit is Quartus4.2 with NiosII1.1.

Can the User Component Editor generate a bidirectional export port??

I have wrote a Verilog program, and in the program there is an "inout" port.

But after I have imported it into the User Component Editor, it can't recognise the "inout" port, and consider it an "input" port.

And I had done the same experiment with a Verilog program of bidirectional PIO generated by SOPC Builder, I got the same result !!!

Can anybody tell me what's wrong with the SOPC Builder??

I had the same problem. I've defined my bidirectional port as input export in component editor and than i've associated to it a bidirectional pin. It works.

My solution is to put the avalon signals directly out the ports, and then I connect my module to the avalon bus outside. And it works well.

But I think that is it a bug in the SOPC Builder?? Can anyone of Altera answer me this question??
