If the net is not fully routed the box will stay yellow. Cm should tell you that at the very bottom bar of the UI. To enable unrouted drc mode go to the Analyze Menu in CM and select Analysis Modes. In the Options tab of the resulting UI select the according checkboxes. ;-) Andy Dave Seymour Sent by: 03/14/2005 09:26 AM Please respond to icu-pcb-forum@xxxxxxxxxxxxx To icu-pcb-forum@xxxxxxxxxxxxx cc Subject [PCB_FORUM] Prop Delay - Analysis Failed On 15.2 I have a net with the PROPAGATION_DELAY set. The electrial constraints form button is "on". In the CM spreadsheet, The cell is yellow and reports that the Analysis failed. What are the reasons that the Analysis could fail? Is there something else to setup?
