Build steps for residual models like UNet?

[MAD-hav-KGP]

I was trying to compile a UNet model with FINN. Based on info I found here, I've replaced the convtranspose layers with upsampling + conv2d layers, and also found an answer referring to the resnet50 build. However, I wasn't able to run the resnet 50 build from finn-examples, and was wondering if there is any general advice on implementing models with residual connections?
