Hi, I've been working on my project for the university (I called it "pymips"). Now I know (with a bit effort) how to code convertible things. But I don't know why the code I get fails when I try to compile it. For example, the converted version of the alu http://github.com/nqnwebs/pymips/blob/master/alu.py is this http://github.com/nqnwebs/pymips/blob/master/vhdl/alu.vhd when I try to compile or check that I get this: (hdl)tin@azulita:~/facu/arq/project/vhdl$ ghdl -a alu.vhd alu.vhd:31:22: no function declarations for operator "and" alu.vhd:33:22: no function declarations for operator "or" /usr/lib/ghdl/bin/ghdl: compilation error what's wrong? thanks Martín |

This might help, from the MyHDL manaul the default simulator for
VHDL is GHDL. You can see in the default config you need to inlcude
the pck_myhdl_*.vhd file as well.<br>

what's wrong?

Probably the reason is that there is no and/or in numeric_std that returns a signed for unsigned arguments. I checked this with 0.7dev, and it seems this bug is solved with an additional cast (I don't remember though fixing this though :-)) I suggest to use 0.7dev by pulling it from mercurial - this should be more or less the 0.7 release for within a few weeks or so anyway, and so you help with getting the bugs out :-) Jan Martín Gaitán wrote: > Hi, > > I've been working on my project for the university (I called it > "pymips").
