The invention relates to the technical field of linear
voltage regulators, and discloses a
layout layout and automatic splicing method capable of configuring LDO modules, which comprises the following steps: S1, planning
Floorplan, drawing each analog module leafcell to obtain an analog module
layout, reserving an interface to a boundary boundary, defining a boundary boundary layer for program identification, and meanwhile, establishing a layout layout and an automatic splicing method of a configurable LDO module, the layout layout and the automatic splicing method of the configurable LDO module, the layout layout and the automatic splicing method of the configurable LDO module, the layout layout and the automatic splicing method of the configurable LDO module; controlling the position of a pin through a layout wiring tool, and operating to obtain a digital module layout; s2, compiling a splicing code, calculating each parameter of each LDO module through a fitting function, splicing the analog module layout and the digital module layout, and respectively obtaining an analog part layout and a digital part layout; and S3, checking the spliced digital part layout and the spliced analog part layout in sequence, and carrying out
design rule checking (DRC) and layout
schematic diagram consistency checking (LVS) after the digital part layout and the analog part layout pass the checking. A stable, rapid and multi-configuration effect is achieved by performing customized drawing on a
simulation layout and performing configurable splicing on the
simulation layout and a digital layout generated by depending on an automatic layout and wiring tool.
