Problem Title:
Mentor: Check Design gives Error: Out of date reference; Version 1 of symbol "gnd", or of
symbol "vcc"

Problem Description:
Urgency: Standard

General Description:

Within pld_da I have my schematic design opened, which was created using
Xilinx A1.5i, and now I am using 2.1i. When I run Check Design I am getting
an error message similiar to the following:

Error: Out of date reference; Version 1 of symbol "gnd" is not the most current (2) for instance: I$3 Error: Out of date reference; Version 1 of symbol "vcc" is not the most current (2) for instance: I$5

Solution 1:

In the A1.5i library the vcc and gnd symbol pin names were
vcc and gnd, but now in 2.1i the pin names have changed
to P and G. So the schematic sheets that have any vcc or
gnd components must be updated by doing the following
from within pld_da:

1) Right-mouse-click in the pld_da session window. (The window
behind the schematic if the schematic is opened.) You may have
to resize the schematic window, or minimzie it.

2) Choose the Update Design option.

3) Either enter in the top level name in the "Enter Top level design name"
dialogue box, or use the Navigator button to select it.

4) Click on the "OK" button to proceed with updating the design.

5) Check the design. It should now finish without errors.

6) Save the updated design.
