get_clock_domain_info (::quartus::sta)

Belongs to ::quartus::sta 1.0

Similar to create_timing_summary, the
get_clock_domain_info command returns a Tcl list of
information about each active clock domain.  Each entry in
the list is a list of four elements: the clock name,
worst-case slack, endpoint TNS, and edge TNS. TNS
istotal negative slack, and it is the sum of
all slacks less than zero for either destination
registers or ports in the clock domain (endpoint TNS)
or for all edges affecting the clock domain (edge
TNS).

By default, this command creates a Setup Summary. This
command can also generate a Hold Summary (-hold),
Recovery Summary (-recovery), Removal Summary
(-removal), or Minimum Pulse Width Summary (-mpw).
