Why has the block RAM and FIFO power usage increased when I migrate from 2013.2 XPE to 2013.3 XPE?
The block RAM modeling has been updated in 2013.3. A portion of the updates associated with the block RAM is the accuracy based upon the block RAM configuration. Specific power savings were updated based on the ENABLE and WRITE Mode setup and based on the WRITE_MODE and WRITE Enable configurations. There has been an increase of approximately 25% (compared to previous estimates) for block RAM and approximately 40% (compared to previous estimates) for FIFO.
The other updates in 2013.3 are:
