18 years agoI've noticed that the largest value I can use for the -divide_by option is 32768 (2^15). If I use 65536 (2^16), then I get these warnings:
warning: the period, rise edge, or fall edge of clock: diag_clk_21 was found to be outside of the range of acceptable time values. the minimum acceptable time value is -2147483.647 and the maximum acceptable time value is 2147483.647. this clock will be ignored.warning: the calculated rise and fall waveform edges for clock: diag_clk_21 were found to be identical (rise: 0.000, fall: 0.000). this clock will be ignored. The source clock is 25MHz. This is what I've found, so yes there are limits.
