Hello. Today I encountered a weird error and I'd like to know if this is a bug/unsupported feature or I'm just doing things wrong
This is the situation. I normally work with huge designs that take a ridiculous amount of time to implement. To overcome this, I use the new ECO flow which allows me to do some basic netlist editing inside the Vivado GUI to produce a bitfile much much faster.
Now lately I've been playing around with the incremental implementation to also get bitfiles faster (using the checkpoint of a previous implementation).
But today, I tried doing the ECO flow using a checkpoint created from an incrementally implemented design and that's when I started to get problems. My goal was to export a net to an output pin, so this is what I did
The error showed up on step 6 with the following message
ERROR: [Common 17-69] Command failed: The specified option is not supported in incremental flow.
Nevertheless, if I re-route the design from scratch, I don't get any errors. Also, if I unroute the design and try to route individual nets I don't get any errors either.
Have you had this issue before? Am I doing something wrong?

Thanks for the reply. The way I use the incremental flow is exactly as described in that AR.
I normally use a 3rd party tool for synthesis, so my procedure is this
In the scenario where I got the error, I had already generated a bitfile using that flow, so all I wanted to do next is to export a net to an output pin for debug.
