Tool Assessment and Qualification Process
The purpose of tool assessment and qualification in DO-254 is to ensure that the tool is capable of performing the particular design or verification activity to an acceptable level of confidence for which the tool will be used. Prior to use of any tools in DO-254 for any design and verification activities, a tool assessment should be performed, and if necessary a basic tool qualification should be documented and recorded.
Code Coverage Tool Assessment and Qualification Documentation Package
Code Coverage analysis can be used to identify sections of source code which have not been executed by the testbench, and determine the sections that are executed more frequently than others. It is significant the Code Coverage tool goes through Tool Assessment and Qualification Process to ensure that it provides accurate coverage counts and results. Aldec provides a package of VHDL test cases and extensive documentation (Tool Operational Requirements, Tool Test Plan, Tool Qualification Accomplishment Summary and Test Analysis Documentation) proving that Code Coverage: Branch and Statement Coverage show accurate coverage counts as expected.
Independent Tool Assessment of HDL Simulator
HDL simulators can be independently assessed by DO-254/CTS. Since the testbench from RTL simulation can be reused by DO-254/CTS as test vectors during in-hardware verification, mapping and matching the hardware testing and RTL simulation results can be easily accomplished.
Independent Tool Assessment of DO-254/CTS
The RTL simulation results obtained from the HDL simulator can independently assess the results of the DO-254/CTS during in-hardware verification. Since the testbench from RTL simulation can be reused by DO-254/CTS as test vectors during in-hardware verification, mapping and matching the hardware testing and RTL simulation results can be easily accomplished.
