FPGA Express: How do you specify slew rate in FPGA Express?
Problem Description:
Urgency: Standard
Slew-rate can be specified on I/O after the design has been elaborated in
FPGA Express.
Solution 1:
After elaborating the design (before optimization), right-click on the implemented
design and select 'Edit Constraints'. This will bring up the constraints window.
The 'Ports' tab will list all the pins for a given design. There is a column
in this display called 'Slew Rate'. Selecting the row that corresponds to
the pin you want, left-click on the box under the Slew Rate column and
select Slow or Fast. Modify the top row to change the default value.
Note: slew rate can only be specified on ports of type output or inout in
FPGA Express
