Hello, After successfully running the

mul32

following the tutorial I was trying to run the flow for a basic verilog adder, getting the following issue: Can anyone please help? I tried changing the

PL_TARGET_DENSITY to 0.59 and 0.60

a different issue arises then. I also tried changing the CORE_HEIGHT Sorry, can't figure out what I'm missing...
