Approaches for protection of HLL simulation models in a circuit design having unprotected high-level language (HLL) program code and first metadata of a shared library of executable simulation models that are based on sensitive HLL simulation models. A design tool determines a first storage location of the shared library based on the first metadata and compiles the unprotected HLL program code into an executable object. The design tool links the executable object with the library of executable simulation models from the first storage location and then simulates the circuit design by executing the executable object and loading the executable simulation models in response to initiation by the executable object.

Protection of high-level language simulation models

A method, computer-readable medium and apparatus for creating a platform-specific logic design from an input design are disclosed. For example, a method includes receiving an input design and an identification of a target device. The method next determines an unconnected external interface of the input design and detects an unconnected external interface of the target device. The method then generates an updated design from the input design. The updated design includes the input design and further includes a connection between the unconnected external interface of the input design and the unconnected external interface of the target device.

Automated generation of platform-specific logic designs for target environments from a common base design

A computer-implemented method of incorporating a module within a circuit design can include, responsive to identifying the module to be imported into the circuit design, automatically identifying each port of the module, displaying a list of the ports of the module, and receiving a user input selecting a plurality of ports of the module for inclusion in an interface through which the module communicates with the circuit design. Responsive to a user input specifying an interface type, the interface type can be associated with the plurality of ports. The interface type can be associated with a port list including standardized ports. Individual ones of the plurality of ports can be automatically matched with standardized ports from the port list. A programmatic interface description specifying the interface for the module can be output.

Creating interfaces for importation of modules into a circuit design

Within a system comprising a processor and a memory, a method of creating a circuit design for implementation within an integrated circuit can include inserting a placeholder block into the circuit design, wherein the circuit design includes a circuit block comprising circuitry and a circuit block interface, and wherein the placeholder block is devoid of circuitry and, responsive to receiving a user input specifying a coupling between the placeholder block and the circuit block, automatically determining a plurality of attributes of the circuit block interface. The method can include automatically generating, according to the attributes and by the processor, a placeholder interface within the placeholder block, wherein the placeholder interface is complementary to the circuit block interface. The placeholder block can be stored within the memory.
