Introduction
Thank you very much for taking EVAL-pSRAM-GW1NR4 as the
development & learning platform. This user guide can help you install the
required software, compile the Demo, and download it to the development
board to test so as to be familiar with the development flow.
Install Software
Install Gowin EDAsoftware (Gowin YunYuan Software) to creat,
compile and download FPGA Demo program. Download the EDA software,
apply for a license, and obtain software user guide at GOWINSEMI website
https://www.gowinsemi.com/en/support/home/. For details on the software
installation method and usage, please refer to SUG100, Gowin YunYuan
Software User Guide.

before the delivery of EVAL-pSRAM-GW1NR4 development board. The
development board can be checked whether to work when it is powered
on.
Plug the 5V power supply into the power socket of the development
board. Switch on the power to start the internal FLASH to load.After
loading is done, eight green LEDs will blink, indicating that the
development board can work.
Compile Demo Program
The LED test program is to demonstrate eight LEDs blinking. Users
can download the corresponding demo at Gowinsemi website:
https://www.gowinsemi.com/en/support/database/. Save the project in the
directory with no Chinese characters. Open and compile this demo using
Gowin YunYuan software.
1. Open the "LED_test.gprj" project and the follows are displayed in the
"Design" window:
GW1NR-LV4MG81C6/I5: Gowin FPGA device part number;
LED_test.v: Verilog code;
LED_test.cst: Physical constraints file.
