2 FPGA development board setup
This document provides instructions for demonstrating the operation of SHA256IP on the KCU105 Evaluation Board. In this demonstration, users can test the functionality of SHA256IP using custom input messages and evaluate its performance via the serial console. The following sections detail the environment setup, test menu and results.
1 Environment Setup
To operate SHA256IP demo, please prepare following test environment.
1) FPGA development board (KCU105 Evaluation Board).
2) Test PC.
3) Micro USB cable for JTAG connection between FPGA board and Test PC.
4) Micro USB cable for UART connection between FPGA board and Test PC.
5) Vivado tool for programming FPGA installed on Test PC.
6) Serial console software such as TeraTerm installed on PC. The setting on the console is Baudrate=115200, Data=8-bit, Non-parity and Stop=1.
7) Demo configuration file (To download this file, please visit our website at www.design-gateway.com).

3 Serial Console
Users can test and monitor the functionality and performance of SHA256IP via the serial console. When the configuration is complete, the SHA256IP demo test menu will be displayed, as shown in Figure 3. Details of each menu are described in topic 4.

4 Test menu and results
4.1 Functional test
The functional test evaluates the SHA256IP to generate a hash from a given input. Users can input a message, which is then processed by SHA256IP to produce a corresponding hash value. The maximum length of the input message is 2047 characters. Additionally, the execution time required for this operation is recorded.
4.2 Performance test
The performance test evaluates the computational efficiency of the SHA256IP when processing large volumes of data. Users can enter the length of repeated ‘a’ character, and then the SHA256IP computes its hash. The execution time is measured to analyze the processing capability under high data loads.
