|/ | | | | | | | | | | | | | | If the REG_INPUTA_CLK and REG_INPUTB_CLK values are set, then we should use the faster setup/hold timings for the 18x8 multiplier. Similarly, check the value of REG_OUTPUT_CLK for whether or not to use faster timings for the output. This is based on how I currently understand the registers to work - if anyone knows the actual rules for when each timing applies please do chime in to correct this implementation if necessary. Along the same lines, this PR does not address the case when the pipeline registers are enabled, since it is not clear to me how exactly that affects the timing.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Trying to parse this invalid LPF syntax: LOCATE COMP "a" SITE "A1" IOBUF PORT "a" IO_TYPE=LVCMOS33; (note missing semicolon on first line) gives an assertion failure in strip_quotes, because the fifth token is scanned as "A1"IOBUF (without a trailing quote). Avoid the problem by detecting extraneous input and issuing a more specific error.

See https://bayimg.com/AAnNKAAGO for an example. The top (magenta) trace is the MCLK line.
