NV30 shown running in hardware....but only at a few KHz...

Just my two cents: i find it hard to believe that the had the COMPLETE NV30 running in FPGA.

Thats the most powerful station IKOS has to offer, at least according to their website, and it had 30M ASIC gate capacity. With NV30 rumoured to have 120M trans, i dont think it would equate to 30M gates only.
 
I wonder how many of the "gates" (or area) of the NV30 is SRAM that probably wouldn't be included in the FPGAs.

If it's 120M transistors they should be able to fit in that 30M gates number. A NAND or NOR gate requires 4 transistors, AND/OR/XOR/XNOR gates requires 6 transistors.

In any case Transistors != Gates.

...and gates on a chip != gates on an FPGA.

For example the library I'm currently using has cells in it which do complex functions (e.g. half adder cell), but would still be termed as 1 gate. The FPGA may not be able to support that function in a single cell, so may use 2.
 
My guess the IKOS model in the Anandtech´s article is capable of 15millions transistors simulation.

Use 6 transistor per gate (average) and it means up to 90 millions transistors, the rest is SRAM.

Dunno but take a look on the IKOS product pages...

System 9
Modularity 9
ASIC Gate Capacity 30M
Memory Capacity 144 Mbytes
Emulation Speed 500 kHz to 2 MHz
I/O Connections 4608
Probing ~120,000
- what does it means? :)
 
Even if the number of transistors per gate varies widely, it's often concidered to be 4 when talking of bulk counts. I've even seen tools which reported the gate count as true transistor count/4 regardles on how many gates the design had.

Regarding the ~120 000 probes.
The IKOS emulator has a bunch of wires going to an AGP card that sits in a PC that thinks the IKOS is a NV30-card. On the other end of the IKOS, there's a connection to a host computer that can look inside the virtual NV30. The 120k probes are likely "virtual probes" that the host computer can put on internal signals. Like a massive logic analyzer.
