I'd like to ask what optimization options need to use to achieve > 190MHz clock speed? please help me, thanks very much.
The project won't "just compile" and achieve >190MHz. Getting timing that high requires using Xilinx's SmartXplorer to brute force it.
Thanks for you hint. I've already tried SmartXplorer with default 7 built-in strategies, but can't achieve above 160MHz result. so, you mean I should use the cost table method to brute force it? thanks.
