MAGMA CTS problem with using "run timing adjust skew"

[praneshcn]

Hi,

I am trying to minimize clock skew in my design and i found a command "run timing adjust skew" which can used in cts. But when i gave the command i got the following error. any suggestions.

mantle[182]:>run timing adjust skew $m $l -effort high -clear
MSG-10 While running 'run timing adjust skew /work/demod/demod /cl013lv -effort high -clear':
CLK-7 ERROR: This command will set latency forces. Latency forces can only be set in 'ideal' clock mode. However, the current clock mode is 'computed.'



thankz

Re: MAGMA CTS PROBLEM

U have set all the clock as propagated instaed of ideal before going for CTS. May be because of this its showing the ERROR/Warning.

Re: MAGMA CTS PROBLEM

" run timing adjust skew" will be useful only in Ideal mode.. (Before CTS)..
U completed ur CTS,. Obviously it is in computed mode now.. U cant use this command when ur design is in computed mode....

Use this cmd before CTS Implementation.. Then Proceed with CTS..
The constraints which is generated by "run timing adjust skew" will be applying during CTS implementation (fix clock)....
