Partially opaque intellectual property (IP) includes source code providing the IP functionality. Meta-comments (pragmas or attributes) are provided with the source code to enable visibility of one or more nodes in the IP. Aliasing of the visibility-enabled nodes may also be provided for using meta-comments in the IP source code. The visibility-enabled nodes may be used by system designers in debugging a system design in either a software simulation environment and/or in debugging of a hardware device implementing the partially opaque IP.

Debuggable opaque IP

Techniques are provided for automatically recommending a suitable programmable IC for a circuit design in response to receiving information about the circuit design. The information can be provided in any desired format. For example, specifications defining the circuit design can be provided in a spreadsheet. As another example, a user can select circuit components for the circuit design from a design library. The information describing the circuit design is compared with information about the features of available programmable ICs. A determination is then made as to which of the available programmable ICs is suitable for the circuit design.
