CTS for design with multiple power domains

fieldy

Hi,

 

I have a power gated domain that I'm trying to implement that I'm having trouble with CTS.

I have 2 power domains : base_domain(always on) and gated_domain(power-gated).

Both domains have multiple clocks in the domains that I'm trying to synthesize clock tree for.

For some reason, when I perform ClockDesign, Encounter places the clock tree cells that belong in the gated_domain in the

base_domain. I tried setting -honorFence true in setCTSMode but it doesn't seem to help. The clock tree starts from the

gated_domain and crosses over to the base_domain. Is there a way to restrict the placement of clock tree 

within its power domain? I cannot have the clock cells cross over from the gated_domain to the base_domain.
