Updated to the latest service pack and I'm seeing a problem I have not run into before. Maybe I'm doing something wrong, but....
Below picture shows pairs of pins routed out to vias on the top layer. After laying these pairs down I now want to continue routing from the via on the bottom layer. I set my active layer to the bottom and click on the ratsnest near the via and my cursor jumps back to the IC pin and wants to route on the top layer. No matter what I try, I can not route from the via. It is sending me back to the IC pin. I have done this numerous times in the past and I'm wondering if it is a "feature" (bug) in the latest release, or is there some setting that I don't have set properly?
In reply to oldmouldy:
I reported it to Cadence and as I was reading your reply, their response came back........... Can't duplicate.
I'll send them the file I'm working on and see if that makes a difference.
I have found that if I route from one pin to the via and stop. I can then click on the rats next to the via and continue on from there, no issue. Once I tie both IC pins to the same via and stop, then try to route from the rats near the via, it jumps back to the IC pin.
We'll see what they have to say.
In reply to TH Designs:
Which appmode are you in? What is enabled inthe Find Filter?If you sent the design to Cadence it's always good to add a script (File >Script >Record) of what you are doing along with setting the AppMode, Find Filter and any Options. This way it's more likely to be reproduced. The only way I can reproduce what I am reading from above is:Etch Edit modeBottom - invisibleSet the active class to BottomSelect the ratIf I have the Bottom visible then the connection from the via starts on the bottom layer.
In reply to Rik Lee:
Tech support was able to verify what I was seeing using the board file I sent them. They are sending the board file to Cadence for evaluation to see if it is an actual problem or whether it is functioning "as designed"........

Bottom is visible.
I know this may be an obvious observation, but did you check your constraints file - 'Physical' tab and make sure the bottom layer line width on the form is not set to "0"? If this is set to "0", it will not allow you to route on that layer.
