:One large CAD package is "SPICE2G6" from U.C. Berkeley.  It's a circuit
:simulator.  Here are measurements of a Sun3 and a Sun4, both running
 
	Spice2G/3C1 is mainly floating point program, while espresso is a
logic minimization program. It should also be kept in mind that
for one reason or another the attached Floating Point Units
on the sun3 series are always slower than their sun4 cousins. If I remember
correctly the latest FPU+ on a sun3/470 is only rated at 1.2MFlops while
the sun 4/390 (FPU2+?)  is rated at something like 2.2 MFlops peak ! ( I don't 
think Sun wants to see its sun3 series giving the sun4s a hard time)
