摘要:
A method of debugging an integrated circuit (IC) can include receiving, within a debugging system implemented within the IC, a debug command from a system external to the IC and, responsive to the debug command, initiating a debug function specified by the debug command for a processor system embedded on the IC. An IC also is provided that can include a programmable circuitry (e.g., a programmable fabric) coupled via an interface to processor system embedded in the IC. A debugging system can be implemented within the programmable fabric to communicate with the processor system via the interface.

Various embodiments of a co-simulation system are disclosed. In one embodiment, a data processing arrangement executes a simulator that simulates a first block of an electronic circuit design. A first clock source generates a first clock signal, and a second clock source generates a second clock signal. The first and second clock signals are independent one from another, and an operating frequency of the second clock signal is dynamically adjustable from a clock control interface. A programmable logic device (PLD) is configured with logic that includes a co-simulation interface clocked by the first clock signal, a second block of the electronic circuit design that is clocked by the second clock signal, and a synchronizer that controls data transmission between the co-simulation interface and the second block.

Methods are provided for processing design information of an electronic circuit design. A single path or multiple paths that are produced by a first design tool are an input for the method. Each path includes an ordered set of element names of the electronic circuit design. Each element name of each path is pattern matched with the names of design blocks of the electronic circuit design produced by a second design tool. Data indicative of a path produced by the second design tool that includes the design blocks that are pattern matched to the ordered set of element names is the output of the method.

A memory access system is described in which local memory units on a reconfigurable chip can be used in conjunction with the system memory. Data path units on the reconfigurable chip can cause data to be swapped in and out of the local memory units as a result of calculations within the reconfigurable fabric. Alternately, a cache-like system can be used so that the data can be read into the local memory unit from the system memory units automatically.
