- Standard Parasitic Extraction Format (SPEF)
The figure shows that SPEF can be generated by place-and-route tool or a parasitic extraction tool, and then this SPEF is used by timing analysis tool for checking the timing, in-circuit simulation or to perform crosstalk analysis
- LEF DEF 5. 8 Language Reference -- 4 - LIP6
A Design Exchange Format (DEF) file contains the design-specific information of a circuit and is a representation of the design at any point during the layout process The DEF file is an ASCII representation using the syntax conventions described in "Typographic and Syntax Conventions"
- DEF file in VLSI Design | Data Exchange Format - Team VLSI
DEF file is used to represent the Physical layout of an Integrated Circuit (IC) in ASCII format A DEF file is strongly connected with the Library Exchange Format (LEF) file So both files are needed for a correct display of physical design

Once you have perfected your layout with the specified grid settings, you can proceed to generate the LEF (Library Exchange Format) file Here are the steps to save your modified layout and extract the LEF file:
- Library Exchange Format | LEF (. lef) File in Physical Design
In this post, we will discuss the LEF file used in the ASIC Design LEF is a short form of Library Exchange Format LEF file is written in ASCII format so this file is a human-readable file A LEF file describing the Library has mainly two parts
- Import . spef file in Spectre - Custom IC Design - Cadence Technology . . .
In the DSPF flow, you simply need to reference the DSPF file from the Setup->Simulation Files form in ADE The port ordering should (generally) be handled automatically because of how the DSPF is included into the design
- extraction of spef using star rc | Forum for Electronics
To get spef you need following inputs, 1) complete DEF (logic with connection) 2) You dont use just tf (is has only cell delays) as this is routed design you use technology file to get real data values of metal and vias aloang with fanout and actual routing delay 3) RC corners with PVT conditions 4)Input from STA (timing input)

# Create the clock tree spec from the sdc file (from synthesis) createClockTreeSpec -output $BASENAME ctstch # Set -routeGuide to use routing guide during CTS

Firstly, we will map the name “Din2_net” as “*2” and use “*2” hence forth, to refer to Din2_net We will come back to how do we calculate the load value of “0 15” *D_NET denotes “distributed net” If we had used a reduced format of the nets, with only single value of resistance and capacitance, it would had been called as “*R_NET”
- ASIC design flow: File extensions
DEF def is used to describe all the physical aspects of a particular file including netlist an the physical location of the chip Example: if we have a complete placement from a floorplanning tool and want to exchange information with cadence cell ensemble or cell3 ensemble, use a def file CIR
