CycloneV PLL and PLL reconfig simulation

I've generated PLL and PLL_reconfig function with Quartus18.1. The PLL receives 20 MHz and sends out 25 MHz. I want to change the frequency of the outcoming signal from 25 MHz to 50 MHz. I'm new wi...

Indeed, there is no such a file. But I have get PLL_20_25.vho for Altera PLL Mega-Function, and PLL_RECONFIG_20_25.hdl for Altera PLL Reconfig Mega-Function. Why file . vho doesn't generate for Altera PLL Reconfig Mega-Function?How can I control it? When I'm trying to simulate the design via Model-Sim10.5B, then no waveform generated by Altera PLL before reconfig and after reconfig.
