Info: Running Quartus II Timing Analyzer
Info: Version 6.0 Build 178 04/27/2006 SJ Full Version
Info: Processing started: Thu Jan 17 12:57:41 2008
Info: Command: quartus_tan --read_settings_files=off --write_settings_files=off led -c led
Info: Started post-fitting delay annotation
Info: Delay annotation completed successfully
Warning: Timing Analysis does not support the analysis of latches as synchronous elements for the currently selected device family
Warning: Found pins functioning as undefined clocks and/or memory enables
Info: Assuming node "clk" is an undefined clock
Warning: Found 1 node(s) in clock paths which may be acting as ripple and/or gated clocks -- node(s) analyzed as buffer(s) resulting in clock skew
Info: Detected ripple clock "clk1" as buffer
Info: Clock "clk" has Internal fmax of 57.8 MHz between source register "\p0:count[1]" and destination register "\p0:count[9]" (period= 17.3 ns)
