13.2 PlanAhead - Does not prohibit certain banks when using part compatability


I am using the PlanAhead tool to perform I/O placement for the XC7VLX585T, FFG1761 and set the "part compatibility" to 485T-FFG1761.

The PlanAhead tool prohibits one of the two HR banks (Bank 12), but leaves bank 13 (which is HR in 585) as available.

Looking at the 7 Series FPGAs Overview (DS180), Table 7, it appears that the 485T, FFG1761 has no HR banks.


This issue has been corrected in ISE Design Suite 13.3.

In ISE Design Suite 13.2 and earlier, there is no work around other than manually verifying that bank constraints are applied to properly prohibited banks when you set the part compatibility option.
