摘要： A method and apparatus for tracing any node in an emulator, including hidden nodes of a circuit design, includes maintaining a correspondence between physically observable nodes and hidden nodes of the circuit design being emulated. The correspondence identifies how values of the hidden nodes are to be determined based on corresponding ones of the physically observable nodes. The value of a hidden node is determined by obtaining the values of the corresponding physically observable nodes and identifying the value of the hidden node based on the correspondence between the corresponding physically observable nodes and the hidden node.

摘要： A crossbar device includes a first set of input lines and a second set of output lines. A plurality of chains of pass transistors are provided to selectively couple the input lines to the output lines in a reduced parasitic capacitive loading manner. Further, memory elements and decoder logic are provided to facilitate control of the selective coupling. Additionally, a low power application of multiple crossbar devices to a reconfigurable circuit block is improved by having each memory element of a crossbar device be provided with a supply voltage higher by a Vth to maintain the input voltage of corresponding output buffers at Vdd. Further, an application of multiple crossbar devices to a reconfigurable circuit block is improved by coupling a control circuitry via a control line to all output buffers of the interconnected crossbar devices to force the output buffers to a known state at power-on.

摘要： A computer system is programmed with logic for automatically removing timing hazards from a circuit design. More specifically, the computer system is programmed with logic for automatically detecting and resolving clock gating as well as clock division timing hazards from the circuit design. In one embodiment, the computer system is further programmed with logic for logically organize timing hazards into levels, after the clock gating timing hazards have been resolved, and then resolving clock division timing hazards recursively. In one adaptation, the computer system is a component of a hardware emulation system.

摘要： An integrated circuit is described as comprising a plurality of logic elements (LEs), each of which having a plurality of outputs, and a partial scan register. The plurality of LEs are operative to generate a plurality of output signals in response to a plurality of input signals correspondingly applied to the LEs. The partial scan register is reconfigurably coupled to select ones of the LEs such that, when enabled, the partial scan register is operative to capture and output on a scan bus a record of signal state values circuit elements emulated by the selected LEs in a particular clock cycle of an operating clock, wherein the partial scan register is enabled with application of a scan clock appropriately scaled to the operating clock.

摘要： An integrated circuit (IC) includes a number of function blocks (FB), of which at least one is re-configurable. Each of the FBs may be a reconfigurable function or a non-reconfigurable function or recursively expanded with additional “nested” function blocks. The IC further includes a number of input pins, a number of output pins, and a number of crossbar devices. The elements, at least at the IC level, are coupled in a manner such that all input signals are provided to the FBs through a first subset of the crossbar devices, all internal signals are routed from one FB to another FB through a second subset of crossbar devices, and all output signals are routed from the FBs to the output pins through a third subset of crossbar devices. To increase routability and speed each of the crossbar device output has a single fanout. Additionally, each of the crossbar devices may provide only one input to each other crossbar device.

摘要： Embodiments of crossbar devices constructed with Micro-Electro-Mechanical Systems (MEMS) switches are disclosed herein. A crossbar device may comprise m input terminals, n output terminals, n control lines and m×n MEMS switches coupled to the n control lines to selectively couple the m input terminals to the n output terminal. Each of the MEMS switches may comprise a contact node coupled to one of the m input terminals, a cantilever coupled to one of the n output terminals, a control node coupled to one of the n control lines to electrostatically control the cantilever to contact the contact node or be away from the contact node using electrostatic attractive or repulsive force respectively. The cantilever and the contact node are configured to remain in contact by molecular adhesion force, after the cantilever has been electrostatically controlled to contact the contact node, and the electrostatic attractive force has been removed. Other embodiments may be described and claimed.
