regarding RC synthesize and retime

[Arvindh19]

Hi ppl
Can I use multiple retime commands in my scripts as follows?

retime -min_area 
retime -min_delay

and what does the retime -prepare do?

With respect to Syntehsize command

can I use the following in my script?

synthesize -to_generic
synthesize -to_mapped
synthesize -to_placed
synthesize -spatial

and can I use the -incremental option in conjunction with all of these? for ex: synthesize -to_generic -incremental

Thanks in advance.

Regards
Arvindh.S

You can use both although may not help too much when used together. Depends on which goal you wish to achieve and should use only that.

I think you need to do some reading on the documentation, although prepare option ideally pre looks at the design for retme oppurtunities and throws info the logfiles and marks flops that it can retime.

Also -incr can only be used with map, spatial and placed options of "synthesize" not with generic.
