If you have experience of Free Software workflow on PIC microcontrollers (particularly assembler and upload) or FPGA (particularly place-and-route) then please could you let me know on or off list.
Hi Mike,
Not done much with PIC - if they will hide their free tool chain away, then they can't expect me to use it.
The Microchip tool chain is non-free. :( On improving my searching, I've found `gputils` which looks to do the job:
Anyone on list with experience of it?
There is also a simulator `gpsim`:
Again, anyone on list with experience of it?
On FPGA, have you seen chiphack.org? There was also a talk at ORCONF last week on free EDA tools. Videos should be up very shortly.
Are the tools all Free Software?
- Quartus II Web Edition
- ModelSim Altera Starter Edition
- OpenRISC 1000 toolchain
Particularly, is the place-and-route bit Free Software?
All vendor supplied FPGA toolchains are heavily proprietary, as are the configuration bitstream formats of all but one (I forget which vendor provides documents for theirs, but the devices have something like 5 LUTs).
It is a sad state of affairs.
Embecosm will be uploading the talks from ORCONF soon and you need to watch Clifford Wolf's, on Yosys, IceStorm and arachne-pnr.

Great links, thanks.
