Remove Unused Peripherals from the RTL Design

The Sapphire RV64 SoC includes a variety of peripherals. If you do not want to use a peripheral,

1. Unselect the peripheral and regenerate the SoC, or
2. Remove the signal name from within the parentheses () in the SapphireSoc_inst definition in the top-level Verilog HDL file. For example, the SoC instantiation has these signals:

.system_i2c_0_io_sda_write          (system_i2c_0_io_sda_write),
.system_i2c_0_io_sda_read           (system_i2c_0_io_sda_read),
.system_i2c_0_io_scl_write          (system_i2c_0_io_scl_write),
.system_i2c_0_io_scl_read           (system_i2c_0_io_scl_read),

To disable I²C 0, remove the signal name in () as shown below:

.system_i2c_0_io_sda_write         (),
.system_i2c_0_io_sda_read          (),
.system_i2c_0_io_scl_write         (),
.system_i2c_0_io_scl_read          (),
