12.3 Drive Strength and Resolution

​

12.3.1 Drive Strength Levels (Strongest to Weakest)

​

Verilog models drive strength for accurate multi-driver resolution.

​

1. supply (Supply drive – VDD/GND)

​

2. strong (Strong driver)

​

3. pull (Pull-up/down resistor)

​

4. weak (Weak driver)

​

5. highz (High Impedence)
