12 years ago --- Quote Start --- You do not want to use PLL lock as a reset signal directly. Not all PLL locked outputs have a debounce/deglitch filter, so they may toggle for a while before they stay in a static state. Download the code associated with this PCIe test http://www.alteraforum.com/forum/showthread.php?t=35678 There's a deglitch/debounce filter in there you can use to "clean-up" the locked signal. You can then decide whether to use the "clean" signal as a synchronous or asynchronous reset signal. Cheers, Dave --- Quote End --- Hi Dave, Thanks very much to mention this. I will be very careful to use the lock of PLL as the reset. I still want to be clear about my question. Let's assume the lock from PLL is a clean signal. Can I write the verilog code as my previous post? Thanks very much.
