Documentation The COTS version v1.03.a is the baseline from which the DO-254 AXI Timer 1.00a comes from. Logicircuit applies the DO-254 lifecycle to this COTS version. As a result of this DO-254 process, the source code will be modified with the goal of achieving 100% code coverage, and the resulting code will be named DO-254 AXI Timer 1.00a. Below are links to the Xilinx® Product Data for the version that was used as the basis, and the Logicircuit Data Sheet of the resulting DO-254 product.
