Alex, You didn't really answer my questions about third-party simulators, so I'm not sure. Do the problems occur if you run virtuoso and then load the OCEAN script? It's probably best if you contact...

When I look at the results of the Innovus place phase, the initial routing solution produced by the earlyGlobalRoute only uses 2 metal layers. Metal 2 and 3. Only one area where the memories have...

Hmm. I agree that's strange. But... Is the design easily routable with just M2 and M3? It seems like if the design can be routed with lower metal layers that would be a good thing because it minimizes...
View ArticleForum Post: RE: Routing layers used by Innovus early global router
Hi Robert. The design is not easily routable. The overall cell density (pre-fill) is >90% and timing is quite tight. There also some large memories that significantly block M1->M4 I am using the...

The Periodic Stability analysis (pstb) does not give you the loop gain in each phase. It gives you the time-averaged loop gain over the whole period, which is what you really want. If you want the loop...
