HDL Multi-section parts are not displaying properly. U1a, U1b etc not seen.

tmd63

When a schematic symbol is placed on a schematic like a quad op-amp, and packaged, other systems will mark them as U1a, U1b, U1c and U1d for example.

In HDL, there is only the pin numbers that shows that a different section is being used. How do we display the section letter for a multi-section part?

    Seem to remember from the training that you have to run packager on your design to assign sections.  More of a CIS person myself.

    Yes. The packager assigns the parts into a package. But KiCAD, Altium, EasyPC all add the lower case letter to a designator to show which part of the package is being used as well as the pin numbers.

    Cadence does not do this! So you cannot see a U1a, U1b, U1c or U1d for a quad package! If you check the attributes, you can see Section 1, 2, 3 or 4 but these are not displayed as letters or even shown on a default package!

    Raised as an issue with Cadence. The alternative was to display the $LOCATION and $SECTION attributes with some delimiter like : or - between them. So they now display U1-1 and U1-2 instead.
