Can I set paths that have recovery error to false path?

In my sopc system, there are always recovery errors, which are from reset syncronizer module to ddr control module. Here is one path: From Node: NiosII_CPU:soc0|NiosII_CPU_reset_clk_domain_sync...

Hi Rbugalho,

Thanks very much for the reply.

I agree with you, setting false path is not a way to solve problem.

I'm just thinking this path might have been syncronized on the DDR controller side, so I could set it to false path that the fit would work better for other paths.

We tested the firmware which has this recovery error in a real board in the past, there was no problem. That's why I'm thinking to set it to false path.

From the name, ddr_clk_ddr_dqs[0] should be a clock from dqs pin of ddr controller, if so, there should be prefix in front of it, for example, "NiosII_CPU:soc0|ddr_sdram:the_ddr_sdram|ddr_sdram_ auk_ddr_sdram:ddr_sdram_auk_ddr_sdram_inst| ...", but in reality, there is not prefix.
