Netlist tools comparison, GOF, Verdi and GateVision

netlist visualization

GOF, Gates On the Fly, GUI netlist debug/ECO tool.
Verdi, RTL and netlist debug tool.
GateVision, Netlist Analyzer.

An experiment has done to compare GOF with Verdi and GateVision's schematic feature. (Verdi has powerful RTL debug feature, this experiment only covered it's netlist processing and schematic engine).
To load 378M bytes netlist files on Pentium 4 Linux machine.
Load time, GateVision has longest time to load, 220 seconds. Verdi 130 seconds. GOF takes 70 only seconds.
Memory usage, Verdi has worst memory usage control. It needs 1.5 G bytes. GOF uses 643M bytes to process the 375M bytes netlists. GateVision runs a program to convert netlist to compressed data format which uses peak as much as 1.4 G bytes. After the conversion is done, it only takes 431M bytes.
Partial Schematic Interactivity, Verdi and GateVision have weak partial schematic interactivity. Users can't control the cells and wires location. GOF has very strong interactivity. Users can change cells position any time and edit/add/delete cells and connections.
ECO capability, GateVision doesn't have ECO features. Verdi/nECO has limited netlist ECO function. GOF has much more complete ECO operations.

Can gof do spare gates eco?

IMHO, ...

1) GOF, Gates On the Fly
---- Personal free ECO utility for Verilog gate-level netlist
---- Focus on interactive ECO

2) Verdi/Debussy
---- Debug platform (e/Vera/SystemVerilog/Verilog/VHDL; PSL/OVA/SVA)
---- Strong in hyperlink, cross-probing between different views, such as
Design:RTL(Netlist)/Schematic/Simulation waveform

3) GateVision
---- Visualization technology
---- Focus on Verilog gate-level netlist visualization

Debussy is best for debugging.

Yes, GOF supports metal only ECO which uses spare gates only. Check the link

1. When GOF is used ...
Does the change in schematics automaticallly reflects in your netlist .. ?

2. Instead of creating a partial schematic in verdi, try to do "trace between 2 points" and then load the schematic in the ECO window.

You can save your ECO operations in netlist format or script format.
GOF can read in timing violation file and draws the violated path automatically which has start point and end point. And you can move the cell position as you like.

The extract-logic-cone feature in GOF is alternative to do partial schematic
