18.104.22.168. Global Network Buffers
- CLK_CTRL_Gn—for Global driver
- CLk_CTRL_Rn—for Regional driver
Buffers to access the global networks are located in the center of each side of the device. Buffering to route a core logic signal on a global signal network causes insertion delay. Tradeoffs 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 is demoted to local routing.
