Did I need to set a proper pin assignment if I running a simulation ?

Hi,

For running simulation, pin assignment is not required, but you may need to run synthesis.

Using your environment I am able to run the simulation passing the ld_debug.

Please check back the step, Normally the fail will occurs if your host is out of memory, the full simulation of "run -all" normally took few GBs on the memory space, I suggest to try clear the memory before re-run
