EXEMPLAR 1999.1x: How to force I/O standards onto ports


Problem Description:
Urgency: Standard

General Description:

I want to use the PCI_33_GTL I/O standard in my design. How
can I force this type of buffer using an Exemplar TCL script, or
from the command line.


Solution 1:

All you have to know is the top level port name and then
an attribute can be used from the command line or from a script.

The following example has a top level port name of data_in:

set_attribute -port data_in -name buffer_sig -value PCI_33_GTL

This attribute must be applied after loading the library, reading the
HDL files, and before optimization.
