UPduino Documentation, Release 0.1
• open fpga verilog tutorial.
Tools
• Icarus Verilog.
• GTKWave.
• Verilator.
UPduino Examples
• XarkLabs SystemVerilog Example <https://github.com/XarkLabs/upduino-example> - demonstrates simulation
and other aspects of a more complete software toolchain
1.1.5 Specifications
The UPduino supports the following features:
• Lattice iCE40 UP5K UG48 FPGA
UPduino Pinout
The UPduino pinout was kindly provided by Xark below.
• G0/G1/G3/G6 refer to Global clock inputs.
• gpio_20 is used for the on-board 12MHz oscillator if the OSC jumper is shorted.
• gpio_35 is the ideal location to supply a clock as this will allow placement of the PLL right next to it.
• If gpio_35 is used as an input, y nything other than a clock, you cannot use a PLL in your design!
• qSPI flash access is possible by shorting the jumpers on the board: note that this uses up gpio_10 and
gpio_20.
