9 years ago --- Quote Start --- I presume the fitter will have more options internally for routing delays between io register and its buffer. The setting of 0/1 is just an extra for user. --- Quote End --- Now I am a bit confused. So how can I make fitter to delay specific bus bit? I am thinking to putting something like that:
# For bus bit 0
set_output_delay -max 1.0
-clock }]
set_output_delay -min -0.5
-clock }]
set_output_delay -max 1.0
-clock
-clock_fall }] -add_delay
set_output_delay -min -0.5
-clock
-clock_fall }] -add_delay
# For bus bit 1
set_output_delay -max 0.5
-clock }]
set_output_delay -min -1.0
-clock }]
set_output_delay -max 0.5
-clock
-clock_fall }] -add_delay
set_output_delay -min -1.0
-clock
-clock_fall }] -add_delay This should give 0.5ns more delay on dataout[1] bit?
