INFO:ConstraintSystem:178 - TNM 'I_CLK100', used in period specification
   'TS_I_CLK100', was traced into DCM_SP instance GEN_CLKSYS/USEDCM.DCM. The
   following new TNM groups and period specifications were generated at the
   DCM_SP output(s): 
   CLKFX: <TIMESPEC TS_GEN_CLKSYS_USEDCM_CLKOUT0 = PERIOD
   "GEN_CLKSYS_USEDCM_CLKOUT0" TS_I_CLK100 / 0.64 HIGH 50%>

WARNING:ConstraintSystem - The Offset constraint <OFFSET = IN 10 ns BEFORE
   "I_CLK100";> [sys_w11a_n3.ucf(18)], is specified without a duration.  This
   will result in a lack of hold time checks in timing reports.  If hold time
   checks are desired a duration value should be specified following the 'VALID'
   keyword.

Done...

INFO:NgdBuild:1222 - Setting CLKIN_PERIOD attribute associated with DCM instance
