General Description: In Chapter 12 (Attributes/Logical Constraints) of the Libraries Guide, the IOSTANDARD attribute states that Virtex-E supports PCI33_5 but does not support LVCMOS2. Is this information accurate?
解决方案
No -- the information is incorrect; however, it was corrected in the 5.1i software release.
Please refer to the Libraries Guide in Version 5 for the correct information on I/O Standards that are supported by Virtex-E.
