Typical device design workflow
←Member specifications · Index↑ · Base root blockspec→
Using blockspecs, a typical device design workflow would be as follows:
- From the product functional specification, identify sets of control functions that can logically be grouped into blocks. These sets of functions might be:
- Replicated in the device, as for example in a mixing console;
- Already existing in other products (or expected to exist in future products);
- Industry standard protocol interfaces.
- Create or find usable blockspec definitions. Such definitions might be:
- Defined in public blockspec libraries;
- Defined in private (i.e. corporate) blockspec libraries;
- Custom-built for the product being designed.
- If necessary, modify found blockspecs to fit requirements exactly.
- Create a new blockspec (
root blockspec) for the device’s root block that:- Instantiates all the component blockspecs as required, and
- Defines individual control objects as needed (e.g. a power on/off control).
- Use the completed root blockspec to drive manual or automatic code generation processes to implement the device’s NCA control API.
