Introduction

The Tiny-XO2 is a small, versatile and cost-effective development platform for Lattice MachXO2 field-programmable gate arrays (FPGAs). It is built around a MachXO2-1200HC FPGA which features 1280 LUTs, 64 kbits of EBR SRAM and one PLL besides various other features[1]. The development board extends the functionality by providing a USB-to-serial converter and a crystal to allow quick and easy prototyping. All I/O pins are available on the .1 inch headers and labelled directly on the board. Figure 2 provides an overview of all the board's functions.

Using Sigasi with GHDL and GtkWave

This video demonstrates a little program I wrote to emulate vcom/vsim using GHDL. It enables Sigasi to check syntax and to simulate using GHDL/GtkWave.
