Patent number: 8434039Abstract: Methods, software, and apparatus for providing a netlist for simulation that includes one or more parameters that are determined by one or more pattern dependent effects. One particular embodiment of the present invention receives a layout of a circuit including one or more MOSFET transistors. For one or more of the MOSFET transistors, spacing between transistors is measured using the received layout and a pattern dependent parameter is determined. This parameter modifies the length of the gate that is used in simulation. In other embodiments, other pattern dependent effects can be used to determine the values of one or more parameters. These parameters may be used to modify gate length, emitter size, resistor width, or other device characteristics.Type: GrantFiled: March 28, 2011Date of Patent: April 30, 2013Assignee: Altera CorporationInventor: Jeffrey Watt

Patent number: 7858469Abstract: The present invention is a trigger device useful, for example, in triggering an SCR in an ESD protection circuit. Illustratively, an NMOS trigger device comprises a gate and heavily doped P and N regions in a P-well on opposite sides of the gate. A first N type source/drain extension and a first P-type pocket region extend from the P region toward the N region with the pocket region located under the source/drain extension and extending under the gate. A second N-type source/drain extension and a second P-type pocket region extend from the N region toward the P region with the pocket region located under the source/drain extension and extending under the gate. Preferably, the gate itself is heavily doped so that one half of the gate on the side adjacent the heavily doped P region is also heavily doped with dopants of P-type conductivity and the other half of the gate on the side adjacent the heavily doped N region is also heavily doped with dopants of N-type conductivity.Type: GrantFiled: September 24, 2009Date of Patent: December 28, 2010Assignee: Altera CorporationInventors: Jeffrey Watt, Irfan Rahim

Patent number: 7465971Abstract: A configuration memory cell (“CRAM”) for a field programmable gate array (“FPGA”) integrated circuit (“IC”) device is given increased resistance to single event upset (“SEU”). A portion of the gate structure of the input node of the CRAM is increased in size relative to the nominal size of the remainder of the gate structure. Part of the enlarged gate structure is located capacitively adjacent to an N-well region of the IC, and another part is located capacitively adjacent to a P-well region of the IC. This arrangement gives the input node increased capacitance to resist SEU, regardless of the logical level of the input node. The invention is also applicable to any node of any type of memory cell for which increased resistance to SEU is desired.Type: GrantFiled: December 5, 2007Date of Patent: December 16, 2008Assignee: Altera CorporationInventors: Lakhbeer S.

Patent number: 7355453Abstract: Techniques are provided for trimming drive current in output drivers to compensate for process variations, model inaccuracies, and/or an off-target process. The actual output drive current is measured on the integrated circuit (IC) at wafer sort or during a final test. Based on the measured output drive current, the total transistor width that is required in the output driver to meet an I/O standard is calculated. A control block controls trimming transistors that are coupled in parallel with main output drive transistors. The control block adjusts the total width of the output drive transistors to bring the total width as close as possible to the desired width. Each I/O driver on a die can be adjusted individually based on its own drive current characteristics. All I/O drivers on a die can be adjusted by the same transistor width based on a single I/O measurement or on multiple I/O measurements.Type: GrantFiled: August 11, 2004Date of Patent: April 8, 2008Assignee: Altera CorporationInventor: Jeffrey Watt
