Creating test environment with UVM for SPI

In order to implement reliable digital system, it is becoming important making tests and finding bugs by setting up a verification environment. It is possible to set up effective verification environment by using Universal Verification Methodology which is standardized and used in worldwide chip industry. In this work, the slave circuit of Serial Peripheral Interface, which is commonly used for communication integrated circuits, have been designed with hardware description and verification language SystemVerilog and creating test environment with UVM.
