CC_PLL Verilog simulation model bug #14

Open tarik-ibrahimovic opened 2 weeks ago

tarik-ibrahimovic commented 2 weeks ago

The provided simulation Verilog model of CC_PLL isn't a correct representation of the true CC_PLL's behavior. Whatever parameters put in when instantiating CC_PLL get lost and the output clock frequency is just half the input.

This can be especially confusing when running simulation of the examples built in with the tools.
