  • Patent number: 9996643
    Abstract: A method of modeling an integrated circuit comprises generating a schematic of an integrated circuit comprising a first circuit component. The schematic comprises a first representation of the first circuit component. The method also comprises replacing the first representation with a second representation of the first circuit component. The second representation includes resistive capacitance information (RC) for the first circuit component. The RC information is based on first RC data included in a process design kit (PDK) file and second RC data included in a macro device file. The second RC data is based on a relationship between the first circuit component and a second circuit component. The method further comprises selectively coloring the second representation of the first circuit component in the schematic based on the RC information. The coloring of the second representation is indicative of whether the integrated circuit is in compliance with a design specification.

  • Patent number: 9348965
    Abstract: A method for circuit design includes a parasitic aware library embedded with one or more parameterized cells. The parasitic aware library is used to insert nets representing some but not all parasitic effects of a circuit into a circuit schematic enabling a single circuit schematic to be used for simulation of the circuit, parasitic verification of the circuit and LVS (Layout Versus Schematic) check. Only the single circuit schematic is required for the circuit design process and to form a mask set. Critical paths of the single circuit schematic are identified and parasitic effects are extracted and inserted into the schematic, enabling a pre-estimation of parasitic verification to be carried out and the LVS check to be carried out using a circuit schematic with some parasitic effects prior to the post-layout simulation in which all parasitic components of the layout are included.

  • Patent number: 8856701
    Abstract: The present disclosure relates to an apparatus and method to generate a device library, along with layout versus schematic (LVS) and parasitic extraction set-up files for connecting with official tools of a design window supported by a process design kit (PDK). The device library comprises passive devices which can be utilized at any point in an end-to-end design flow from pre-layout verification to post-layout verification of an integrated circuit design. The device library allows for a single schematic view for pre-layout verification but also post-layout verification, thus allowing for pole or pin comparison, and prevents double-counting of parasitic effects from passive design elements by directly instantiating a device from the device library for a verification step. An LVS and parasitic extraction graphical user interface (GUI) allows for incorporation of the generated device library into a pre-existing PDK without any modification to the PDK. Other devices and methods are also disclosed.
