Data Setup
需要准备的data
physical library
physical library 文件提供 macro/IO/st的物理信息。
- cell size/shape
- pin locations/layers
- routing blockages(over-the-cell)
lef 文件是重复使用 的physical library文件
logic library
logic library 文件提供 macro/IO/std cells 的timing 和 logic 信息 。
- functionality
- timing
- logic drc i.e. max_transition/max_fanout/max_capacitance
- power consumption
- PG pin information for UPF suppor
.lib/.db是经常使用的logic library file。
lib类型:
- standard cell (and , nor ,DFF)
- Memory(SRAM,DRAM,ROM)
- IP(PCIe,ddr)
- IO
- PLL
