In Stratix® III and Stratix IV devices, the PLL output counters can access global and regional networks as shown in the respective device handbooks. Note, global networks can only be accessed from PLL output counters C0-C3. All PLL output counters can access regional networks.
Tables 6-8 and 6-9 show the global and regional connectivity in Clock Networks and PLLs in Stratix III Devices (PDF).
Tables 5-5 and 5-6 show the global and regional connectivity in Clock Networks and PLLs in Stratix IV Devices (PDF).
