Document Table of Contents Global Network Buffers

Routing paths allow you to identify global network buffers that fail timing. Buffer locations names reflect the network they drive.
  • CLK_CTRL_Gn—for Global driver
  • CLK_CTRL_Rn—for Regional driver

Buffers that access the global networks are in the center of each side of the device. Buffering to route a core logic signal on a global signal network causes insertion delay. Trade-offs to consider for global and non-global routing are source location, insertion delay, fan-out, distance a signal travels, and possible congestion if the signal demotes to local routing.
