Update of Project Details

posted Oct 31, 2017, 9:47 AM by andi6510 The FPGASID Project

The project details now have a chapter about the Alpha test and about the latest news about start of sales in 2018.

FPGASID can be purchased in 2018!

This is good news!

FPGASID will be available for everybody!

I have found partners who will take FPGASID into their webshop. We are now busy with the preparations to start the production. Current plan is to have FPGASID on the shelves beginning of 2018.

Starting from today you can make a reservation for your personal FPGASID and be among the first owners!

Another two amazing [videos]!

Release 5 available

posted Jul 19, 2017, 12:37 PM by andi6510 The FPGASID Project

In the download section you'll find release 5 now.

This release fixes two problems:
  1. In MONO mode The envelope generators are occasionally out-of-sync between both channels.
  2. The SYNC bit in the voice control registers was not handled correctly.

I recently made an experiment: I added a second FPGASID to my testing machine by using an expansion-port breadboard-PCB. This setup allows me to use 4 SID instances together. I will add more details on this experiment soon on the project details page but until then you can checkout the result here:

Another Interview [video]

There is another interview about FPGASID done by in cooperation with Nerds&Geeks. As usual it is in german language (sorry for that) and can be found in the latest show from

The show including the interview. The part about FPGASID starts around timecode 22:45.

FPGA revision 2 binaries available

posted Mar 19, 2017, 4:14 AM by andi6510 The FPGASID Project

After the first reports from the Alpha testers I prepared a bugfix release to fix the following issues:
  • POTX and POTY had been swapped.
  • Source selection of the EXTIN input was not matching the register specification.
  • Test bit handling was fixed.
  • Fixed advanced digi playback as used in Coma Light.
  • Adressing at DE00 collides with external modules such as the 1541U2 or some midi modules.
    Note: This fix is still a workaround because it disables all reading from the DE00 address range. A final fix will be available in the next hardware release.

The new FPGA binaries are available on the Download Page together with the flashing tool and instructions how to do the flashing.

Alpha Testers have received their devices

posted Mar 12, 2017, 2:10 PM by andi6510 The FPGASID Project   [ updated Mar 12, 2017, 2:12 PM ]

All participants in the alpha test phase have now received their devices and have started to check the FPGASID functionality. During this phase we will collect all smaller and bigger problems that occur and find appropriate fixes for them. Based on this experience we will be able to release an improved version with all the bug fixes included.
The general feedback is very positive so far.

First lot arrived today!

Today I received the first lot of FPGASID_proto1 boards from our manufacturer:

The first lot! As you can see through-hole parts will still have to be mounted manually.

Once everything is built up, flashed and tested, these boards will get shipped to the Alpha-Testers. These poor ones are already waiting for so long now to finally get their test objects...

Finally the first lot of FPGASID_proto1 is being built

Before the Christmas holidays I received a first sample of the FPGASID_proto1 boards from our manufacturer. The power-up of this board took quite some time. Maninly caused by a bigger issue with a CMOS-latchup of the output amplifier. But in the end this issue could be solved. After fixing some smaller FPGA bugs the prototype is now up and running. There is no reason why it should not go to the Alpha testers for detailed testing now.
Yesterday I gave the GO to our manufacturer to build up the complete lot of FPGASID_proto1 boards. This will take until mid of February.
