Keywords: PAR, P&R, xflow, implement, ISE, EDK, integration, runtime

When I have an EDK project instantiated in an ISE project, what different implementation options will be used?

Solution

The notable differences between EDK and ISE are:

EDK: map -pr b -timing; par -ol high
ISE: map -pr off; par -ol std

To ensure that the EDK cores perform as intended when inside of an ISE design, change the ISE settings to match the EDK settings that are listed above.

NOTE: The -timing switch is on by default for Virtex-5, so there is no need to add this switch when targeting Virtex-5 devices.
