In my design, I have several clock domains. The standard cell vendor's design rules suggest to use shielding for clock nets with > x MHz, which for me applies to just a single clock.
I can implement shielding for all clocks by defining a custom route_type with -shield_net and specifying it in cts_route_type_top, etc. However this global settings always applies to all clocks. So I'm looking for a equivalent setting for just one clock.
Alternatively, I considered going via the routing rules for clock net. But it seems once CTS segments the net by inserting the buffers, the property is not moved over to the newly created CTS_* nets.
Any suggestions?
