hi maliha, nice to hear from you.  we have Lattice ECP5 up and
running using nextpnr-ecp5, and we have Digilent Arty A7-100t
up and running using nextpnr-xilinx.

the instructions are all here on how to install things *please read them
and follow them*.  (we have found consistently and repeatedly that
errors are almost exclusively caused by people not following the
instructions precisely and exactly).


in your case you want at least yosys, nextpnr-xilinx and nextpnr-ecp5
but for building the HDL you should follow the "devscripts" page


if you want to connect a JTAG (FT232r) to your ECP5 board you will
need to follow - or adapt - this:


and we have a *notes-only* page where we are collating information
on getting microwatt up-and-running


bear in mind that libresoc.v can be compiled to be **DIRECTLY**
compatible with microwatt.v as a literal drop-in replacement, which
was what was done here:


if you are in touch with University of Oregon you can gain access
to the Silicon Server which has one Arty A7-100t connected to it
and will soon have 4 more.  let me know and i can make an
