TO the Mentor crew,
We have common circuits defined in the library that are hierarchical blocks. In 2007 netlist flow, we can place the circuits, connect them, annotate them, and the operation of these circuits behaves as expected. Now when we try to use these in 9.x series releases, netlisting results are very poor. Netlister is disconnecting/isolating nets that it shouldn't. It appears that documentation does not address this situation. So to the Mentor crew, what is the process for using these?
