How to decrease the speed of a servo motor?

the servo has 1-2 ms duty cycle, and 20 ms refreshing frequency, bidirectional, non-continuous, 180 degree. It's Sg90. Using 100 Mhz Board clock and already divided it. And this's a part of pwm cod...

Hello there ,

I get chance to go through your RTL ,Looks only constant value for duty cycle is implemented.

Here is the RTL attached for variable angle (i.e duty cycle) and its simulation result

I dont know your application and how you wanted to change the different angle , but for example below I just created a port and given an input through test bench.

Simulation result also shown increasing / decreasing angles.

Thank you ,
