A method and system for enabling a designer to more easily convert a model of a dynamic system instantiated using floating-point representation such as has been created in a high level design language to fixed-point code suitable for execution in a programmable processor or logic array.

Automatic floating-point to fixed-point conversion

A device receives code for a technical computing environment, and receives conditions for executing the code. The device performs a static analysis of the code, based on the conditions, to generate static analysis information for the code, and executes the code in the technical computing environment based on the conditions. The device determines coverage information associated with the executing code, where the coverage information provides a measure of completeness associated with the executing code. The device compares the static analysis information and the coverage information to determine confidence information associated with the coverage information, and outputs or stores the coverage information and the confidence information.

Code coverage and confidence determination

A computing device may obtain usage information relating to an execution of a function within code. The usage information may include a set of input values and an output value obtained based on executing the function using the set of input values. The computing device may further determine that the function has been executed a particular quantity of times using the set of input values and obtaining the output value, and may generate a unit test, for the function, based on determining that the function has been executed the particular quantity of times using the set of input values and obtaining the output value.
