Known Issues

(Xilinx Answer 22027) PAR displays: "INFO:Par:62 - Your design did not meet timing"

(Xilinx Answer 22042) PAR will place the clock pin and DCM on opposite sides of the chip, causing timing failures

(Xilinx Answer 22043) "ERROR:Place:207 - Due to SelectIO banking constraints, the IOBs in your design cannot be automatically placed."

(Xilinx Answer 22048) When using 32-channel or more polled core, timing cannot be met

(Xilinx Answer 22028) BitGen results in "ERROR:PhysDesignRules:755 - IOB comp <TX_DTPA(16)> at location <AH34> is VCCO"

(Xilinx Answer 22046) Spartan-3 and Spartan-3E designs need DCM phase shift

(Xilinx Answer 22052) When simulating design example, upper bit of TMOD is undefined

(Xilinx Answer 22053) When simulating design example, data might be sent to channels not used by the core
