FPGA logic lock and increase frequency

GDeXi

In my design, there are two parts running at different frequencies, and one of them has been debugged stably without any problems. Now I want to lock down the part without problems to reduce compilation time and increase frequency as much as possible.I haven't done this kind of work before. All I want to ask is what I need to do in the software, and whether there are corresponding tutorials and documents for reference. It's better to use the series of aria 10 and stratix10

Set the part of your design that is done as a design partition: right-click it in the design hierarchy in the project navigator and set it as a design partition. You can create a Logic Lock region for it as well, but once you set it as a design partition, you can choose to reuse the post-fit netlist to prevent it from changing. See the block-based design user guide for info on incremental block-based compilation and the linked online training:

Firstly, any reason u want to increase the frequencies on one particular design partition?

Are you using singal tap for debugging? Does your timing closed before you signal tap?
