Filed:

Mar 31, 2005

Appl. No.:

11/096024

Inventors:

Joshua Ian Stone - Santa Clara CA, US
Jonathan B. Ballagh - Longmont CO, US
Roger B. Milne - Boulder CO, US
Nabeel Shirazi - San Jose CA, US

Assignee:

Xilinx, Inc. - San Jose CA

International Classification:

G06F 17/50

US Classification:

716 4, 716 5, 716 6, 703 14

Abstract:

A first block, a second block, a shared memory, and a third block are generated in a circuit design in response to user input control. The first block is coupled to the second block, the second block is coupled to the shared memory, and the shared memory is coupled to the third block in response to user input control. During one cycle of a simulation, the second block, in response to the first block, accesses a set of scalar values in the shared memory using scalar accesses. During one cycle of the simulation, the set of scalar values is transferred between the second block and the first block. During the simulation, the shared memory is accessed by the third block using scalar accesses.

International Classification:

G06F 17/50

US Classification:

703 14, 703 13

Abstract:

Co-simulation of a circuit design includes simulating a first subset of blocks of the circuit design on a software-based co-simulation platform, simulating a second subset of the blocks of the circuit design on a hardware-based co-simulation platform, and maintaining coherency for a memory block of the circuit design between a first representation of data in the memory block on the software-based co-simulation platform and a second representation of the data in the memory block on the hardware-based co-simulation platform. Coherency is maintained by managing mutually exclusive access to the memory block from the first subset of blocks and the second subset of blocks.

International Classification:

G06F 9/44

US Classification:

717127, 717130

Abstract:

An introspection tool monitors the execution of software. The operating system is being executed using an executable of a software source code file. The software source code file is associated with one or more additional source files. The introspection tool detects a trigger in a user script pertaining to monitoring of the execution of the software. The introspection tool identifies an additional source file that corresponds to the trigger in the user script and causes the additional source file to be compiled. The compiling of the additional source file generates debug information that pertains to the trigger and the introspection tool analyzes the debug information to respond to the trigger in the user script.
