I'm still trying to use constraints with range propagation, but I can't get it to work properly, and I haven't found any documentation. It require support. There could be an issue with range propagation when applying constraints to the variables.

There are two main areas of improvement. * False negatives and false positives. * The speed of the validation itself. Another area I see for improvement is scalability, particularly when dealing with large software systems. While Polyspace is effective for individual components and smaller applications, its performance can be impacted when analyzing entire systems all at once. There are limitations with handling large-scale applications.

The run time analysis process must be improved. If we do not run with the main loop, it generates its own main and doesn’t allow developers to modify the execution sequences. The solution must provide more flexibility to the developers to manipulate the runtime analysis tools. The developer must be allowed to modify the main sequence. It will be very easy for them to test their use cases. Otherwise, Polyspace generates a random main file and executes all the functions randomly.
One of the main disadvantages is the time it takes to initiate the first run. Usually, there are a lot of errors initially, and you need to remove dependencies, such as compounded dependencies, to have an initial run. When we compared different tools, we found that the only drawback of Polyspace is the lead time required to have an output. There's something that can bypass the red errors. This is because you cannot base the policy solely on the presence of a red line or error. Sometimes, this mocks other errors from being reported.

The speed is slow based on the bandwidth of the server we are using. The solution could be faster. 500KB of C-files will take 35 minutes to get results, and this could be sped up. Only .XML files are available for importing. I'd like the data to be taken from any format.

There is room for improvement in automation related to the policies. We can work on scripting so that the tool automatically pops up, and with just a minimal amount of user input, we can repeat the execution. While manual processes are fine, automation is also required in today's industry, where time constraints exist in every delivery. Automation could be a challenge, but it is necessary for improvement. In the next release, I would like to have an automated testing environment integrated with Polyspace Code Prover, which can be activated with a single click.
Polyspace Code Prover is a sound static analysis tool that proves the absence of overflow, divide-by-zero, out-of-bounds array access, and certain other run-time errors in C and C++ source code. It produces results without requiring program execution, code instrumentation, or test cases. Polyspace Code Prover uses semantic analysis and abstract interpretation based on formal methods to verify software interprocedural, control, and data flow behavior. You can use it on handwritten code,...
