摘要： A smaller mask programmable gate array (MPGA) device derived from a larger field programmable gate array (FPGA), comprising: a layout of transistors and a plurality of interconnect layers substantially identical to a smaller region of the FPGA; and input/output pads matching a subset of the input/output pads of the FPGA; wherein, a design that is mapped to said smaller region of the FPGA device using said subset of input/output pads by a user programmable means can be identically mapped to the MPGA by a hard-wire circuit. Such a gate array further comprises a mask programmable metal-circuit in lieu of a user programmable configuration circuit of the FPGA; and a logic block to input/output pad connection in lieu of a logic block to a register at the boundary of said smaller region to an input/output pad connection of the FPGA.

摘要： Memory modules implemented on an FPGA device are re-implemented to improve the performance of the device, such as to reduce logic delays. One or more logic blocks of the FPGA device that realize the logic function of a memory module or portion of a memory module are desirably selected. Based on the outcome of a timing analysis, the most critical signal pin of the selected logic blocks may be identified. Methods of deriving the memory module re-implementation for various types of the most critical pins are disclosed. Procedures are described for integrating physical timing analysis, memory transformation, placement, and routing, as well as for the selection of logic blocks for re-implementation.

摘要： Programmable routing structures to couple physical memory nodes to logical memory nodes in embedded multi-port memory FPGA's are disclosed. In a first embodiment, a plurality of physical domain nodes couples a plurality of variable node sets in a logical read domain, wherein a configuration element activates one of the sets and selects a fixed input or an address signal to decode the data read. In a second embodiment, a plurality of physical domain nodes couples a plurality of variable node sets in a logical write domain, wherein a configuration element activates one of the sets and couples a fixed input or an address signal to an enable signal of a driver device to decode the data written. A third embodiment provide logical read and logical write functions for a single port in a multi-port physical memory array, wherein the logical read data width and the logical write data width can be independently configured, and wherein the read and write functions share common address lines.
