Encounter crashes

asicman

 Hi,

 I'm new to Encounter and I'm trying to get familiar with it. Encounter crashes when I try to use Wroute (global and final routing). Here is the output:

  • Hi Brad Tree, After doing the routing I realized that the wroute should not have been used. I am learning to use Encounter so I'm going a lot of experimenting with the program. I hope you don't mind if I ask a few questions and would appreciate whatever assistance you can provide: -When is says: *WARNING* design has no clock net *WARNING* design has no power net *WARNING* design has no ground net I guess this is saying that I did not use encounter power planning to properly place my ground and power nets? But would this cause wroute to fail? -I read in some tutorials that we need an io file to specify the io pads, but I have however read some others which design without using the io file. Would this be something that is absolutely needed for the final design? After I used nanoroute (tsmc 018 technology) on my design, I see that it made connections to the boundaries of the chip for the io ports. Does this imply that the io file is not necessary? Thank you. -
