A system and method for generating a membership profile for a personalized website is disclosed. An online services provider uses the interest engine to generate a questionnaire and polls. A new user provides responses that include answers to the questionnaire and polls. A profile engine generates a membership profile based on the answers. A newsletter engine generates personalized newsletter information including a number of users that provided each answer. In response to an online services provider selecting the recipients for the newsletter, the newsletter engine either generates the newsletter and transmits it to the recipients or the newsletter engine transmits the contact information to the online services provider.

Generating personalized websites and newsletters

A system and method for compressing trace data from an emulation system. Scan chains may receive trace data from configurable logic blocks inside one or more emulation chips, and the data received from the scan chains may be compressed. Where delta compression is used, the scan chains may also perform a delta detection function. Alternatively, delta detection may be performed using the outputs of the scan chains. In addition, event detectors may be implemented within or outside of the scan chains. Compression of the trace data may include receiving a plurality of data sets and performing compression along cross-sections of the combined data sets.

Compression of emulation trace data

Systems and methods facilitate accurate and rapid simulation of software by periodically saving simulation states and design stimuli for use as a replay model. Divergences from the stored information may be detected during subsequent re-executions, which can in turn be run using the saved stimuli and states.

Simulation of software

A tool for emulation systems that obtains the state values for only discrete partitions of a circuit design. When a partition is being emulated, the emulation system obtains the input values for the specified partition at each clock cycle and the state values for the specified partition at intervals. Using the state and input values with a software model of the specified circuit design partition, the tool calculates the state values for the partition at every clock cycle. The software model may correspond to the partitioning information used to implement the circuit design across multiple configurable logic element devices, such as FPGAs. Thus, each software model may correspond to the portion of a circuit design emulated on a discrete FPGA integrated circuit.
