Notes:
The pin-to-pin timing information from ORCA Foundry version 9.2 and later is more accurate than this table. For earlier versions of ORCA
Foundry, the pin-to-pin timing parameters in this table should be used instead of results reported by ORCA Foundry.
This clock delay is for a fully routed clock tree that uses the primary clock network. It includes both the input buffer delay, the clock routing to the
PFU CLK input, the clock→Q of the FF, and the delay through the output buffer. The delay will be reduced if any of the clock branches are not
used. The given timing requires that the input clock pin be located at one of the four center PICs on any side of the device and that the direct
FF→I/O routing be used.
If the clock pin is not located at one of the four center PICs, this delay must be increased by up to the following amounts:
OR2C/2T04A = 1.5%, OR2C/2T06A = 2.0%, OR2C/2T08A = 3.1%, OR2C/2T10A = 3.9%, OR2C/2T12A = 4.9%, OR2C/2T15A = 5.7%,
OR2C/2T26A = 8.1%, OR2C/2T40A = 12.5%.
Speed grades of -5, -6, and -7 are for OR2TxxA devices only
