The design is then routed. This is quite simple due to the crossbar structure of the device. For each edge in the netlist:
- If dedicated (non-fabric) routing is used for this path, configure the destination's input mux appropriately and stop.
- If the source and destination are in the same half of the device, configure the destination's input mux appropriately and stop.
- A cross-connection must be used. Check if we already used one to bring the source signal to the other half of the device. If found, configure the destination to route from that cross-connection and stop.

- If an I/O buffer is connected to analog hard IP, fail with an error if it's not configured in analog mode.
- Some signals (such as comparator inputs and oscillator power-down controls) are generated by a shared mux and fed to many loads. If different loads require conflicting settings for the shared mux, fail with an error.
- If DRC passes with no errors, configure all of the individual cells in the netlist based on the HDL parameters. Fail with an error if an invalid configuration was requested.

Finally, generate the bitstream from all of the per-cell configuration and write it to a file.

Great, let's get started!
- If you don't already have one, you'll need to buy a GreenPak4 development kit. The kit includes samples of the SLG46620V (among other devices) and a programmer/emulation board. While you're waiting for it to arrive, install GreenPak Designer.
-
Download and install Yosys. Although Clifford is pretty good at merging my pull requests, only my fork on Github is guaranteed to have the most up-to-date support for GreenPak devices so don't be surprised if you can't use a bleeding-edge feature with mainline Yosys.
-
Download and install gp4par. You can get it from the Github repository.
-
Write your HDL, compile with Yosys, P&R with gp4par, and import the bitstream into GreenPak Designer to program the target device. The most current gp4par manual is included in LaTeX source form in the source tree and is automatically built as part of the compile process. If you're just browsing, there's a relatively recent PDF version on my web server.
-
If you'd like to see the Verilog that produced the nightmare of a schematic I showed above, here it is.
-
Be advised that this project is still very much a work in progress and there are still a number of SLG46620V features I don't support (see the manual for exact details).

I love it / it segfaulted / there's a problem in the manual!
Hop in our IRC channel (##openfpga on Freenode) and let me know. Feedback is great, pull requests are even better,
You're competing with Silego's IDE. Have they found out and sued you yet?
- Nope. They're fully aware of what I'm doing and are rolling out the red carpet for me. They love the idea of a HDL flow as an alternative to schematic entry and are pretty amazed at how fast it's coming together.
-
After I reported a few bugs in their datasheets they decided to skip the middleman and give me direct access to the engineer who writes their documentation so that I can get faster responses. The last time I found a problem (two different parts of the datasheet contradicted each other) an updated datasheet was in my inbox and on their website by the next day. I only wish Xilinx gave me that kind of treatment!
-
They've even offered me free hardware to help me add support for their latest product family, although I plan to get GreenPak4 support to a more stable state before taking them up on the offer.

So what's next?
-
Better testing, for starters. I have to verify functionality by hand with a DMM and oscilloscope, which is time consuming.
-
My contact at Silego says they're going to be giving me documentation on the SRAM emulation interface soon, so I'm going to make a hardware-in-loop test platform that connects to my desktop and the Silego ZIF socket, and lets me load new bitstreams via a scriptable interface. It'll have FPGA-based digital I/O as well as an ADC and DAC on every device pin, plus an adjustable voltage regulator for power, so I can feed in arbitrary mixed-signal test waveforms and write PC-based unit tests to verify correct behavior.
-
Other than that, I want to finish support for the SLG46620V in the next month or two. The SLG46621V will be an easy addition since only one pin and the relevant configuration bits have changed from the 46620 (I suspect they're the same die, just bonded out differently).
-
Once that's done I'll have to do some more extensive work to add the SLG46140V since the architecture is a bit different (a lot of the combinatorial logic is merged into multi-function blocks). Luckily, the 46140 has a lot in common architecturally with the GreenPak5 family, so once that's done GreenPak5 will probably be a lot easier to add support for.
-
My thanks go out to Clifford Wolf, whitequark, the IRC users in ##openfpga, and everyone at Silego I've worked with to help make this possible. I hope that one day this project will become mature enough that Silego will ship it as an officially supported extension to GreenPak Designer, making history by becoming the first modern programmable logic vendor to ship a fully open source synthesis and P&R suite.
