openCologne and birth of new ULX (ULX5M)
2025-09-19 , Tesla

Talk about collaborative project that had a goal of creating series of extension boards for Olimex FPGA board, porting ULX3S examples to GateMate FPGA, creating ULX5M that will host GateMate FPGA chip, and helping with HW and samples in birth of fully open source tool chain for Cologne GateMate FPGA chips.


In this project in collaboration with ChiliChips*ba, Intergalaktik and RadionaOrg we have designed a new iteration of the popular open hardware ULX-boards (ULX5M) This version is featuring GateMate chips, which is compatible with the widely used CM4 form factor - so it can be slotted into many existing designs instantly. This opens up this strategic new FPGA target for a broader audience. In addition, the project make a portfolio of entry level projects that selectively put GateMate resources to good use, including its unique SerDes. Be they in RTL or HLS, implemented as pure hardware FSMs, or by using HW/SW co-design and SoC techniques, or integrated with LiteX - delivering a variety of real-life use cases.

Goran Mahovlić (electronics tech) worked for years in repair shop for informatics and bank equipment. Moved on to a developer for low power wireless technologies (LoRA/nbIOT) and measuring systems. Currently self employed in Intergalaktik d.o.o. working on opensource HW solutions, mostly FPGA boards. With constant urge to take apart any device within reach and find out it’s secrets, Goran is equally successful at hardware and software hacking, from cheap products, up cycling old tech, to serious work in technology and microprocessor development. He is a tech coordinator at Radiona. In past, Goran led a number of accomplished workshop and presentations, regular member of Radiona projects and exhibitions, lead and founder of Radiona SmartZG network. Among his work is founding the Lemilica.com portal, for which he writes.
