Why do I see the following error "AutoSweepControllerPMAAnalog constructor failure" in the Stratix V GX and Arria V GX transceiver toolkits when running the AutoSweep function?

Description

Due to a bug in the Quartus II software version 11.1sp2 and earlier, you may see a "AutoSweepControllerPMAAnalog constructor failure" error in the Stratix® V GX and Arria® V GX transceiver toolkits when running the AutoSweep function. This is due to the following reason:

When changing the datarate in the transceiver PHY you must leave a white space between the datarate value and "Mbps" ie

"2500 Mbps" is correct.

"2500Mbps" is incorrect.

This will be fixed in a future version of the Quartus II software.
