General Description: Version 1.111 of the Virtex-II Speed Files became available on July 18, 2002, after the release of 4.2i Service Pack 3 (which contained version 1.105). All users should download and install the new version.
Note that 4.2i Service Pack 2 was released with speed file version 1.100. (Please see (Xilinx Answer 12201) for more information.) Therefore, when you upgrade from speed file 1.100 to 1.111, the Virtex-II speed files are affected by two upgrades:
1. The changes from 1.100 to 1.105 2. The changes from 1.105 to 1.111
(NOTE: All adjustments are included in the latest speed file version, so you may install version 1.111 on top of 1.100 without installing version 1.105 in between.)
The highlighted changes in Virtex-II Speed Files Version 1.111 are:
1. TPHFD for XC2V2000, XC2V3000, and XC2V4000 devices is changed to 0 from a positive value for the -4 speed grade. 2. Horizontal and Vertical Long Line delays are adjusted for the -6 speed grade. 3. The multiplier parameter for STEP0 for the -6 speed grade is made equal to STEP1 -6. 4. Support for MINs (-0 speed grade) is added.
