simulator (verilator) does not compile

[bmentink]

I tried running "make bootstrap" for j1a .. but it fails ..

make bootstrap
make -C verilator

Verilator version?

[jamesbowman]

Right.. seems most likely.

My Verilator is 3.856 and after the build I get:

$ grep __DOT__ram_prog verilator/obj_dir/Vj1a.h 
        VL_SIG16(v__DOT__ram_prog[4096],15,0);

[bmentink]

The version giving the error is:

Verilator 3.886 2016-07-30 rev verilator_3_884-13-gb4a7e46

The grep above gives "VL_SIG16(j1aDOTram_prog[4096],15,0);"

Can I give an other help?

Mine's Verilator 3.856 2014-03-11 rev verilator_3_855-19-g749ff02 Which works. If you're on debian you can downgrade to it - I'm just using the prebuilt version ubuntu/debian has. Possibly worth raising as a regression bug against Verilator - since the newer version breaks our code.

There is a way to get the old naming back: just add an option --l2-name v to verilator. Did not try with the older versions though.

[jamesbowman]

Just tried it with my old Verilator (3.856):

%Error: Invalid Option: --l2-name

Looks like this changed in 3.884:
