Clock networks in RC

archive

Hi.
This question is related to myazdani's question.
I'm looking for the equivalent command of DC's "set_ideal_network" especially in connection to clock networks - as far as considering the literature, I've understood clock networks are automatically treated as ideal so I have few questions I'd be happy to get an answer on:
1. Is what I wrote correct - are clock networks automatically treated by RC as ideal?
2. How can I manually set and unset this property on any net I desire? I haven't been able to find the answer in the manual.

Thank You,
Adi.

  • 1) Yes, clock networks are ideal by default.

    2) I think you want to set the ideal_network attribute, or do set it with SDC. See the RTL Compiler
    Attribute Reference Manual

    ideal_network
    ideal_network {true | false}
    Default: false
    Read-write attribute. Sets the network of the specified driver pin to an ideal network. The pin
    must be a driving pin. This attribute propagates through combinational gates, latches, and
    hierarchical boundaries, unlike the ideal_driver attribute.....etc.
