摘要： A method is for designing an accelerator for digital signal processing including defining a software programmable fully pre-laid out macro by pre-laying out with a fixed topology a control logic of the DSP accelerator to obtain a fully pre-laid out control logic. The method further includes defining a hardware programmable partially pre-laid out macro by customizing a configurable layout area, thereby mapping a computational logic based on computation kernels related to an application of the DSP accelerator. A partially pre-laid out computational logic is therefore obtained.

摘要： Circuits and methods use clock gating to reduce power consumption in select parts of a structured ASIC. A clock distribution network includes a deterministic portion, a configurable portion, and one or more clock gating circuits. The deterministic portion employs a predetermined arrangement of conductor segments and buffers for distributing a clock signal and a clock enable signal to a plurality of predetermined locations on the device. A clock gating circuit, connected with the deterministic portion, may be placed at any of the predetermined locations, or at any location within predetermined areas associated with the predetermined locations. The clock gating circuit produces a gated clock signal output. A configurable portion and/or subportion distributes the gated clock signal output to logic elements. Depending on the value of the clock enable signal, operation of the logic elements may be suspended.

摘要： A tool for designing integrated circuits that optimizes the placement and timing of memory blocks within the circuit. Given a manufactured slice that has a number of blocks already diffused and logically integrated, the memory generation tool herein automatically considers the available diffused memory and the gate array of the slices to configure and optimize them into a customer's requirements for memory. The memory generation tool has a memory manager, a memory resource database, a memory resource selector, and a memory composer. Together these all interact to generate memories from the available memories within the memory resource database. The memory composer actually generates the RTL logic shells for the memories, and outputs the memory designs in Verilog, VHDL, or other tool synthesis language. Once a memory is created, it is tested. Upon successful testing, the memory manager updates the memory resource database to indicate the successfully tested memory is no longer available as a resource for the generation of further memories. A design integrator may review the memory designs output and further integrate the memory, its timing, testing, etc. with other blocks and functions of the integrated circuit.

摘要： A method for designing and using a partially manufactured semiconductor product is disclosed. The partially manufactured semiconductor product, referred to as a slice, contains a fabric of configurable transistors and at least an area of embedded memory. The method contemplates that a range of processors, processing elements, processing circuits exists which might be manufactured as a hardmacs or configured from the transistor fabric of the slice. The method then evaluates all the memory requirements of all the processors in the range to create a memory superset to be embedded into the slice. The memory superset can then be mapped and routed to a particular memory for one of the processors within the range; ports can be mapped and routed to access the selected portions of the memory superset. If any memory is not used, then it and/or its adjoining transistor fabric can become a landing zone for other functions or registers or memories.

摘要： Various embodiments include approaches for analyzing a customer design for an application specific integrated circuit (ASIC). In some cases, an approach includes: determining performance requirements of the customer design; querying a test screen database for the performance requirements of the customer design, the test screen database having failure thresholds and associated test screens for detecting the failure thresholds for a set of ASIC devices; generating a filter database including select failure thresholds and associated test screens for the performance requirements of the customer design; and selecting a set of test screens from the filter database based upon a yield cost criteria in forming the ASIC.
