you should try it on the sim

not going to get an opsis out tonight, will play again on the weekend

Should I send your Atlys back with this guy or my parents?

I wonder what it would so in the aim simulator

I doubt it simulates a MiSoC DDR ram core :-P

mithro: you can run the entire SoC (including the MiSoC DDR ram core) with verilator, you can expect 1MHz speed, which is proably enough to develop software

The m-labs guys use clang for artiq which uses a or1k

shenki: see above

shenki: still probably faster then MOOSE ;-)

mithro: hah, moose, that's a blast from the past

shenki: that apparently runs under verilator and can be set up with a or1k CPU --cpu_type or1k

nice

verilator is the project that compiles hdl to binaries?

or am i thinking of ghdl

Title: Intro - Verilator - Veripool (at www.veripool.org)

Verilator is the fastest free Verilog HDL simulator, and beats most commercial simulators. It compiles synthesizable Verilog (not test-bench code!), plus some PSL, SystemVerilog and Synthesis assertions into C++ or SystemC code. It is designed for large projects where fast simulation performance is of primary concern, and is especially well suited to

generate executable models of CPUs for embedded software design teams.

cool

so it runs ok on your laptop? Or you need to use a big machine?

shenki: NFI - never used it

but I think by the sounds of it, it would work okay on any modern machine

The verilator page looks like a blast from the 1990s :P

shenki: Florent did a recording of it running https://asciinema.org/a/18224

what? he's simulating the ethernet device?!

that's cool

Seems so

Anyway, bed time for me

good night
