I found another issue where gowin_unpack.py fails with an error.
(<class 'KeyError'>, KeyError('RPLLB1'), <traceback object at 0x7ff14de41800>)
It is in the definition "def tile2verilog(dbrow, dbcol, bels, pips, clock_pips, mod, cst, db):" in section:
elif typ.startswith("RPLL"):
name = f"PLL_{idx}"
pll = mod.primitives.setdefault(name, codegen.Primitive("rPLL", name))
for paramval in flags:
param, _, val = paramval.partition('=')
pll.params[param] = val
portmap = db.grid[dbrow][dbcol].bels[bel[:-1]].portmap
for port, wname in portmap.items():
pll.portmap[port] = f"R{row}C{col}_{wname}"
It works fine when bel = "RPLLB1", but as soon at the second digit at the end comes in it fails. I changed "portmap = db.grid[dbrow][dbcol].bels[bel[:-1]].portmap" to "portmap = db.grid[dbrow][dbcol].bels[bel[:5]].portmap" and then it runs through without problems.
Attached is the bitstream I'm using. It is converted from a binary format back to the text format by me.

@pepijndevos I'm not sure if you get notified when new comment is added to a closed issue, but I added some to my other issue to point out my ideas on the documentation.
