SPF--Standard Parasitic Format
DSPF--Detailed Standard Parasitic Format
RSPF--Reduced Standard Parasitic Format
SPEF--Standard Parasitic Exchange Format
SBPF -- Synopsys Binary Parasitic Format

总结: SPF,DSPF,RSPF均为Candence格式,均不包含crosstalk C的信息,不可用于PT si.

DSPF 有详尽的RC信息,size比较大,比较接近SPICE netlist.

RSPF是reduced SPF.It represents each net as an RC "pi" model.RSPF causes the PrimeTime tool to calculate an Elmore delay for every pin-to-pin interconnect delay.

SPEF是OVI出的标准格式,被IEEE采用,同样可以划分为DSPEF和RSPEF. SPEF包含了net 之间的cap,可以用来计算crosstalk.用于PT Si.

SBPF是二进制格式,由Synopsy所出.size较小,读的比较快,可以用使用Synopsis的软件写出此格式.

PrimeTime can read DSPF, RSPF, and SPEF and can automatically detect the format
from the file header. PrimeTime can read SPEF versions IEEE 1481-1997, IEEE
1481-1998, and IEEE 1481-1999.
