https://alteraforum.com/forum/attachment.php?attachmentid=14980&stc=1 I am trying to create a 1kHz output using cascaded clocks.I however get this error message in both 17.0 and 17.1. Error: WTH!!!/n while executing "parse_tcl_data $rule_name $reference_list" (procedure "my_set_rbc_check" line 21) invoked from within "my_set_rbc_check OUTPUT_CLOCK_FREQUENCY $param_args" (procedure "get_advanced_pll_legality_solved_legal_pll_values" line 21) invoked from within "get_advanced_pll_legality_solved_legal_pll_values $device_part $ref_clk [get_parameter_value output_clock_frequency$val] $fractional_vco_multiplier $c..." (procedure "validation_callback" line 264) invoked from within "validation_callback" Here is what I have setup. Any advice appreciated! https://alteraforum.com/forum/attachment.php?attachmentid=14980&stc=1 Thankshttps://alteraforum.com/forum/attachment.php?attachmentid=14980&stc=1

Yeah.I chose to actually use 100Mhz and play with settings till I got errors to go away. I ended up having to multiply and divide off 100Mhz clock and string out 5 divide by 10's to actually get it to compile. Divide by M with a Multiply N of 1 didn't seem to ever want to work. I just played with M/N and multiple C's to get something to not error. N of 1 didn't want to ever work. Top frequency of 50Mhz didn't really want to work either. Thanks for the reply.
