Timing analysis and power analysis reports can be generated once implementation is complete. The PAR step is simple yet effective as well, however I did not test (yet) how PAR performs once the device utilization reaches a higher percentage.

In the following GowinSynthesis is assumed to be the selected synthesis engine. I strongly doubt that anyone will use Synplify Pro for GOWIN FPGA’s. The synthesis tool can be set to either GowinSynthesis (included with GOWIN FPGA Designer) or Synplify Pro (external synthesis tool by Synopsys). The design flow is very simple and offers just the most basic options.

Both VHDL and Verilog are supported (allegedly up to SystemVerilog-2017). The ToolchainĪll steps from HDL to bitstream are handled by GOWIN FPGA Designer, a graphical IDE which offers a project based design flow. Almost all user IO pins are utilized by the LCD interface if it is used, so there are not many pins left which could be used to get a video signal into the FPGA anymore. Regarding the LCD interface I am unsure how this would be useful, except for generating some fancy test patterns. Like most of Sipeed’s latest development boards the Tang Nano comes with a USB-C connector, thus a USB-C cable is required to use the board without unnecessary tinkering. costs just about 5 $ (like the Longan Nano).4 pin JTAG header (split into 2 x 2 pins left/right of the USB-C connector).USB- JTAG downloader/debugger (via USB-C connector).The Tang Nano offers the following features: The GW1N-1-LV is the smallest member of GOWINs “Little Bee” series, which consists of small footprint instant-on FPGA devices for IoT and interfacing solutions. GOWIN is another Chinese chip manufacturer entering the FPGA arena, like Efinix and Anlogic. The Tang Nano is a very very low cost FPGA development board by Sipeed featuring a GW1N-1-LV FPGA produced by GOWIN Semiconductors.
