Patent number: 10089425Abstract: A system and method is disclosed in an emulation environment that dynamically remaps user designs. In one embodiment, a request is received to load an integrated circuit design to be emulated in a desired partition within the emulator. The emulator automatically determines the availability of the partition requested. If the partition is not available, the design is dynamically remapped to a different partition that is available. In another embodiment, clocks associated with the integrated circuit design are also dynamically remapped. In yet another embodiment, the user can control the size of the partitions (e.g., the number of printed circuit boards in a partition).Type: GrantFiled: February 3, 2016Date of Patent: October 2, 2018Assignee: MENTOR GRAPHICS CORPORATIONInventors: Eric Durand, Gregoire Brunot, Estelle Reymond, Laurent Buchard

Patent number: 8868974Abstract: A system and method are disclosed for generating triggers within a hardware emulator. The system allows for dynamic reconfiguration of the trigger generation scheme during emulation. In one aspect, input probe signals are received on an address port to a memory from an integrated circuit within the emulator. The memory outputs from a data port, data, which is addressed, at least in part, by the input probe signals. The data output from the data port may be sent through further combinatorial logic or directly connected to a logic analyzer and represents trigger information. In another aspect, the trigger generation scheme may be reconfigured dynamically during emulation. For example, where the memory is a dual-port RAM, an emulation host can write to the memory to perform the reconfiguration.Type: GrantFiled: January 30, 2012Date of Patent: October 21, 2014Assignee: Mentor Graphics CorporationInventors: Gregoire Brunot, Charles Selvidge

Patent number: 7822909Abstract: A system and method are disclosed for crossbar switching in an emulation environment. The switch is designed to coordinate scheduling between different crossbars in the system and to be dynamically reconfigurable during operation. In one aspect, a crossbar switch includes a switching matrix and an array of control cells. The control cells use a high-frequency clock to perform high-speed switching and a low-frequency clock in order to initiate a switching sequence. The low-frequency clock initiates the sequence at a time coordinated with other crossbars in the system to optimize scheduling. In another aspect, the control cells include a memory containing control bits for the switching matrix. The memory may be reconfigured without stopping traffic management through the crossbar switch. In yet another aspect, the high-frequency sequence may provide for the ability to loop.Type: GrantFiled: April 10, 2009Date of Patent: October 26, 2010Assignee: Mentor Graphics CorporationInventor: Grégoire Brunot
