Info: Running Quartus II Classic Timing Analyzer
Info: Version 7.0 Build 33 02/05/2007 SJ Full Version
Info: Processing started: Thu Apr 24 14:31:04 2008
Info: Command: quartus_tan --read_settings_files=off --write_settings_files=off div2 -c div2
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
Info: Clock "clk" has Internal fmax of 76.92 MHz between source register "q" and destination register "q" (period= 13.0 ns)
Info: + Longest register to register delay is 8.000 ns
Info: 1: + IC(0.000 ns) + CELL(0.000 ns) = 0.000 ns; Loc. = LC1; Fanout = 2; REG Node = 'q'
Info: 2: + IC(0.000 ns) + CELL(8.000 ns) = 8.000 ns; Loc. = LC1; Fanout = 2; REG Node = 'q'
Info: Total cell delay = 8.000 ns ( 100.00 % )
Info: - Smallest clock skew is 0.000 ns
Info: + Shortest clock path from clock "clk" to destination register is 3.000 ns
Info: 1: + IC(0.000 ns) + CELL(3.000 ns) = 3.000 ns; Loc. = PIN_87; Fanout = 1; CLK Node = 'clk'
Info: 2: + IC(0.000 ns) + CELL(0.000 ns) = 3.000 ns; Loc. = LC1; Fanout = 2; REG Node = 'q'
Info: Total cell delay = 3.000 ns ( 100.00 % )
Info: - Longest clock path from clock "clk" to source register is 3.000 ns
Info: 1: + IC(0.000 ns) + CELL(3.000 ns) = 3.000 ns; Loc. = PIN_87; Fanout = 1; CLK Node = 'clk'
Info: 2: + IC(0.000 ns) + CELL(0.000 ns) = 3.000 ns; Loc. = LC1; Fanout = 2; REG Node = 'q'
Info: Total cell delay = 3.000 ns ( 100.00 % )
Info: + Micro clock to output delay of source is 1.000 ns
Info: + Micro setup delay of destination is 4.000 ns
Info: tco from clock "clk" to destination pin "clk_div2" through register "q" is 8.000 ns
Info: + Longest clock path from clock "clk" to source register is 3.000 ns
Info: 1: + IC(0.000 ns) + CELL(3.000 ns) = 3.000 ns; Loc. = PIN_87; Fanout = 1; CLK Node = 'clk'
