SPI Mode-3 Slave (CPOL=1, CPHA=1) 8-Bit
About this block
Simulate it in the Verilog IDE
SPI Mode-3 Slave (CPOL=1, CPHA=1) 8-Bit is a Verilog reference block in the Interface Protocols catalog. UART, SPI, I2C, and other serial or peripheral protocol interfaces. Marked Hard: a larger reference. Simulate the packaged testbench before you change the RTL.
This IP provides a robust, synchronous SPI Mode-3 slave implementation. Key integration points include proper handling of the asynchronous sclk input via synchronization and ensuring adequate reset duration. The module is lightweight, suitable for standard 8-bit peripheral communication, and includes a ready flag for easy host integration.
- Choose Open in IDE. RTL Studio loads the packaged workspace for SPI Mode-3 Slave (CPOL=1, CPHA=1) 8-Bit.
- Read the Verilog module in the editor. The catalog line for this block: SPI Mode-3 Slave (CPOL=1, CPHA=1) 8-Bit.
- Run the packaged testbench with the in-browser Verilator simulator, then open the VCD in the waveform viewer.
- Run Yosys in the same IDE for a generic netlist. Sky130 liberty mapping is a separate Pro library option.
RTL Studio is the Verilog simulator and IDE around this block: Slang lint, Verilator, VCD waveforms, and Yosys, in the browser. Simulation guide · Yosys guide.
