Computer-implemented method and computing system for designing integrated circuit by considering timing delay
A method includes performing, using a processor, a synthesis operation to generate a netlist from input data about an integrated circuit, placing and routing, using the one processor, standard cells defining the integrated circuit using the netlist, to generate layout data and wire data, extracting, using the processor, parasitic components from the layout data, and performing, using the processor, timing analysis of the integrated circuit according to timing constraints, based on the layout data and the wire data.
REFINEMENT OF AN INTEGRATED CIRCUIT DESIGN
A processor receives an expression of design refinement intent with regard to an entity forming a part of a modular circuit design. The entity is defined by a hardware description language (HDL) file, and the expression of design refinement intent identifies an intent region within an implementation of the entity and specifies replacement logic for the region. Based on the expression of design refinement intent, the processor automatically modifies the HDL file by replacing logic within the intent region with the replacement logic. The processor then performs logical synthesis to generate a gate list representation of the modular circuit design as modified.

Detecting out-of-bounds violations in a hardware design using formal verification
A hardware monitor arranged to detect out-of-bounds violations in a hardware design for an electronic device. The hardware monitors include monitor and detection logic configured to monitor the current operating state of an instantiation of the hardware design and detect when the instantiation of the hardware design implements a fetch of an instruction from memory; and assertion evaluation logic configured to evaluate one or more assertions that assert a formal property that compares the memory address of the fetched instruction to an allowable memory address range associated with the current operating state of the instantiation of the hardware design to determine whether there has been an out-of-bounds violation. The hardware monitor may be used by a formal verification tool to exhaustively verify that the hardware design does not cause an instruction to be fetched from an out-of-bounds address.

Verification of hardware design for data transformation pipeline
Methods and systems for verifying, via formal verification, a hardware design for a data transformation pipeline comprising one or more data transformation elements that perform a data transformation on one or more inputs, wherein the formal verification is performed under conditions that simplify the data transformations calculations that the formal verification tool has to perform. In one embodiment the hardware design for the data transformation pipeline is verified by replacing one or more of the data transformation elements in the hardware design with a function element which is treated as an unevaluated function of its combinational inputs by a formal verification tool such that during formal verification the function element will produce the same output for the same inputs, and formally verifying that for each transaction of a set of transactions an instantiation of the modified hardware design for the data transformation pipeline produces a set of one or more outputs that matches a reference set of one or more outputs for that transaction.
