  • IC6.1.6 Virtuoso Space-Based Mixed-Signal Router (VSR)
    Virtuoso Space-Based Router (VSR) is routing solution integrated into the Virtuoso Layout Suite, which provides a comprehensive set of routing features for a variety of layout tasks. One major design task for layout designs is chip/block assembly routing in mixed-signal analog top (AoT) designs. What's new in Virtuoso IC6.1.6? VSR routing ...

  • Re: Differences between pins from digital and analog views of a schematic
    Hello -G, which IC and EDI version do you use ? Since you're talking about layout views I assume you work on an Open Access Database. Is you're PDK Mixed Signal enabled - means do you have your technology LEF available as an OA library referencing the Base PDK?   Cheers Andreas

  • Re: Export LEF via problem
    Hello Gangadhar, Did you manage to export a LEF from Virtuoso meanwhile? Does the view name exist (please check with the library manager) ? The LEF export uses the foundry section of the technology library - is the via defined ? You could use CIW - Technology Manager - Dump to write out an ASCII text file and search for the ...

  • Re: Config files
    What tool version do you intent to use? The lib.defs isn't needed using EDI11. The cds.lib file is read in automatically using the open Access database.   Cheers Andreas

  • Re: open the GUI
    You can't open a GUI starting with nowin. The graphic initialization doesn't happen if you start with -nowin. Alternative start encounter without nowin, use the win off command to disappear the GUI and win to raise it again.   Cheers   Andreas

  • Managing Inherited Connections with CPF in Virtuoso
    Let's assume you are managing a schematic-driven top level design in Virtuoso and you want to import a digital block Verilog netlist into Virtuoso. This is a very common use model in mixed-signal implementation. While the Layout Database is saved in Open Access (OA), the optimized Verilog netlist needs to be imported into Virtuoso. Why use ...
