XPLA Professional - How do I estimate the Icc for a CoolRunner design?


Keywords: XPLA, Professional, CoolRunner, fitter, Icc, Idd, estimated

Urgency: Standard

General Description:
How do I calculate the estimated Icc for my design and target the
CoolRunner device?


Once the design has been compiled and fit to the target CoolRunner
device, follow these steps:

1. Click the TimeSim..." button. This will invoke the timing simulator.

2. Use the simulator to build up the stimulus file that your part will see
in normal operation. Pay careful attention to clock frequency and
actual signal bandwidth.

3. Select ICC | Run from the menu bar to launch the Icc calculator.
The results will be placed in a box at the bottom right corner of the
simulator GUI. If you wish, you may also inspect a file that has been
created called *.icc, which contains Icc information at varying time points.

NOTE: This Icc value is an estimated average power consumption
based upon your design file and your simulation file.
