How to change use clock on nets?

spach

Hi,

     I used CTS to buffer signal nets in my design at place stage. once the buffering was over I loaded the actual CTS spec and proceed furthur but these nets r having use clock property. Now My design is fully routed, Can any one tell a procedure to change use clock property to signal for these nets.

  • Hi Bob,

    thank u for u r reply.

    I am working on a hierarchical design. I need to do buffering on nets across partitions. i have written some db scripts to get startpin and corresponding endpn and used cts spec as shown below(no need of balancing b/w nets). i preffer CTS than BTS as CTS takes less run time.


    AutoCTSRootPin core/*/startpin
    SetDPinAsSync YES
    RootInputTran  100.0ps
    MinDelay       300.0ps
    MaxDelay       800.0ps
    MaxSkew        250.0ps
    SinkMaxTran    100.0ps
    BufMaxTran     100.0ps
    Buffer         BFX71
    #
    NoGating       NO
    LeafPin
    + core/*/endpin

    .............................

    once it was over i cleared the spec. and read the actual clock spec.

    i need to find all nets created by above CTS and change its property to signal.
