A technique for synthesizing digital circuit designs by incorporating timing convergence and routability considerations. In one aspect, the invention provides a system and programmatic method for generating a circuit design from a functional specification according to at least one design objective. An intermediate representation of the functional specification is formed. The intermediate representation is analyzed for identifying a physical instantiation that will possibly result in unacceptable interconnect delay or congestion. Functional units are allocated from among a plurality of candidate functional units for performing operations of the intermediate representation. Operations are scheduled to occur at specified times on said selected functional units. An architectural representation of the circuit design is formed according to results of scheduling.

A code generator and multi-core framework are executable in a computer system to implement methods as disclosed herein, including a method for the code generator to automatically generate multi-threaded source code from functional specifications, and for the multi-core framework, which is a run time component, to generate multi-threaded task object code from the multi-threaded source code and to execute the multi-threaded task object code on respective processor cores. The methods provide transparency to the programmer, and during execution, provide automatic identification of processing parallelisms. The methods implement Consume-Simplify-Produce and Normalize-Transpose-Distribute operations to reduce complex expression sets in a functional specification to simplified expression sets operable in parallel processing environments through the generated multi-threaded task object code. The result is a code generator which compiles transparent declarative code into multi-threaded code and that in the process identifies and assigns parallel processing paths to improve overall processing performance.

A method and apparatus are set forth for defining and validating feature policies in an execution system, such as a communication system. The method includes entering user policies described in a straightforward manner (e.g. using a Web browser and user-understandable language) in such a way that they can be translated into a formal executable language. The user policies are then translated into an executable feature language such as the IETF's CPL. The user is then either compelled or provided with an option to validate the overall feature set before it is uploaded to the execution system. If validation is selected, the features are translated from CPL into another format, such as FIAT, from which it is possible to detect common feature specification errors. The FIAT detected errors are then analyzed in a manner that is aware of the expectations and common errors of naive users, and interpreted to determine possible errors as errors that are common to naive users. These errors are reported to the user (e.g. via the Web interface) in terms that are understandable to naive users and compatible with how the policies were originally described. The user is provided with options to either accept the interactions as they are, repair them manually or to accept a recommendation of an automatic correction. Unlike conventional systems, where feature interactions are solved in the same way for all users, the selected resolution is personalized in the present invention to satisfy the end-user's intentions, independently of how others solve similar conflicts. The features are uploaded to the execution system.

A method is provided for exploring alternative architectures for partitioning computer system resources to execute multiple task specifications. An initial master task graph is formed from the multiple task specifications, the initial master task graph including at least one hierarchical task with pointers to either AND sub-task graphs or XOR sub-task graphs. The initial master task graph is processed to provide a selected number of final master task graphs, each of the final master task graphs comprising a list of AND task graphs. A family of architectures is generated for each of the final master task graphs, each of the architectures generated for a given master task graph being capable of executing every AND task graph included therein. The degree of resemblance in composition, functional capability or performance resulting between architectures from different master task graphs is a function of the correlation between the contents of these master task graphs and not of concern to the user of the aforementioned method.
