Hi, What can I do if get DRC errors in a file generated by DPR? Look at the files I've attached. Type: >make extbusdp.drc -> to make Design Rules Checking Or step by step, by typing: >make extbusdp.vst >make extbusdp.ap >make extbusdp.drc I think there's no enough space to routing, but I don't know if it can be modified. I've change the order of the instances to get a routable configuration, and used -o option in DPR, but the errors persist. Thanks in advanced, ANDRES FARFAN ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
