System for communications link components

摘要

Design systems are provided to assist users in designing circuits that include communications links. A communications link may include a transmitter link subsystem, a receiver link subsystem, and a channel subsystem that interconnects the transmitter and receiver subsystems. A user may specify global link performance characteristics such as bit error rate and data rate. Measured link subsystem performance characteristics may be gathered and stored in a database as probability distribution functions. When analyzing a link, known link subsystems parameters supplied by the user may be used to retrieve appropriate link subsystem performance data. The retrieved link subsystem data and the global link performance data may be analyzed and used to produce recommended subsystem limits. A logic design system may use information on a user's logic design and the recommended limits in producing programmable logic device configuration data.

1. A method of producing configuration data for a programmable integrated circuit that contains a transmitter, comprising:
obtaining user input specifying an operating characteristic for a receiver that is to receive data from the transmitter in a communications link when the transmitter is used in a system; based on the user input, retrieving a receiver jitter probability distribution function; and generating configuration data for the programmable integrated circuit using the receiver jitter probability distribution function.
