DCM_RST_PW_MIN
DCM_RST_PW_MAX
DCM_CONFIG_LAG_TIME
This limit only applies to applications that use the DCM DLL outputs (CLK0, CLK90, CLK180, CLK270, CLK2X, CLK2X180, and CLKDV).
The DCM DFS outputs (CLKFX, CLKFX180) are unaffected.
This specification is equivalent to the Virtex-4 DCM_RESET specfication.This specification does not apply for Spartan-3E FPGAs.
This specification is equivalent to the Virtex-4 TCONFIG specification. This specification does not apply for Spartan-3E FPGAs.
