Summary

This library contains a hardware module which implements SHA-512, written in VHDL. Also included are two .do files for verifying correct operation of the SHA-512 core module. An SHA-512 package has been written in VHDL which defines common shifting operations as defined in the original NIST document, which can be found here:

VHDL

The VHDL files assume you are compiling entities to a library named “dsaves”.
This was done to avoid naming collisions. Because libraries in VHDL are a virtual construct, you may have to work with other software you are using (eg. Modelsim, QuestaSim, Xilinx ISE, etc) to create the library “dsaves” and compile the design units to that library. Alternatively, you can change the “dsaves” library to “work”.
