e-Versatile Research Stick for peoples

Description

With the rising of high quality opensource tools for FPGAs new opportunities are emerging to discover and build better digital architectures. This stick is intended as lowest cost tool for anyone who desire to explore & research the world of modern digital systems. It can be used to develop, test and benchmark fairly large digital designs, straight using a complete opensource toolchain end to end.

It can close the gap between emerging trend of high level generated systems (automatic reinforced exploration of arhitectures) and the lack of end to end toolchain harvesting a real FPGA for final feedback.

Let Here Be Dragons !

Specs:

• Small size 16x40mm usb stick
• Generous 85k LUT FPGA logic space
• Holds 1Gbyte DDR3 memory with x16 wide access
• USB3 5Gbps/s data access over x32 wide independent FIFO
• USB2 outband (same usb port) permanent JTAG and UART independent access
• Full opensource HDL flow usig YoSYS suite

Can be used in any USB port right from the tips of fingers, no cables, no wires but full control.

Progress:

• 23-Apr-2020 A batch of 50 PCB arrived. Thank you WellPCB PTY LTD !
• 20-Dec-2020 Second iteraton of PCB has been done, schematics and pcb design are updated.
• 20-Jan-2021 Announcing OLIMP having e-VEREST as demo board.
• 17-Aug-2021 Third iteration of PCB has been done, design is updated.
• 10-May-2022 Due to severe global shortage crowd source batches aren't possible until >2023.
