Chip Maker Gets $35 Million Judgment

Neoflexycurrent writes "The Ninth Circuit Court of Appeals has affirmed a $35 million judgment against Clear Logic for violation of the Semiconductor Chip Protection Act of 1984. The court concluded that the jury properly rejected Clear Logic's argument that it had legitimately reverse engineered Plaintiff Altera Corporation's mask work design to create cheaper application-specific integrated circuits."

    Altera makes chips that can be programmed to do different things (FPGAs).

    Clear Logic made "application specific integrated circuits" - ie they only do one specific thing that the customer needs, but are cheaper than programmable chips if you buy enough.

    The issue here is that Clear Logic's mechanism for receiving the design from the customer and making it into a chip is to use the programming data (bitstream) for an Altera chip. Then the data is used together with an image (mask) copied from an Altera chip to create the ASIC.

    The ruling is that Clear Logic's use of the mask in building the ASIC is not legitimate reverse engineering, but illegal re-use of Altera's IP.

    FYI: Clear Logic seems to have been dead since 2003.

    Ninth Circuit affirms $35 million judgment against semiconductor manufacturer

    Case is rare appellate decision under Semiconductor Chip Protection Act of 1984

    Altera Corporation filed suit in the U.S. District Court for the Northern District of California against Clear Logic, Inc., a competitor in the semiconductor industry. Altera alleged that Clear Logic had violated the Semiconductor Chip Protection Act of 1984, 17 U.S.C. 901 et seq. ("SCPA"), by using the bitstream generated when programming Altera programmable logic devices to create application-specific integrated circuits. A jury found in favor of Altera, and awarded more than $30 million in damages, plus an additional $5 million in interest and costs.

    Clear Logic appealed to the Ninth Circuit, arguing that the trial court improperly instructed the jury regarding the affirmative defense of legitimate reverse engineering, which is provided for under the SCPA. The court affirmed, however, holding that certain misstatements of the law in the jury instructions were harmless error.

    The trial court's instructions initially defined "legitimate reverse engineering" to allow copying and analyzing only "non-protectible concepts or techniques" embodied in a mask work. This was an incorrect statement of the law, but the court concluded that further instructions adequately provided correction. The later instructions explained that "it is permissible [under the SCPA] to reproduce 'a registered mask work' as a step in the process of creating an original chip, so long as the purpose of reproducing the chip is appropriate."

    Accordingly, the court held that the jury was able to properly conclude that the Clear Logic mask works incorporated into the application-specific integrated circuits were not original, but were copies prohibited under the SCPA.

      The mask is like a "negative" for a film. You can think of the chip as the silicon equivalent to the paper used when projecting a film negative onto a photograph.

      In this case, the mask was probably used as a starting point -- FPGA's (Field Programmable Gate Array) have switches that control gates for interconnects between logic units and PGA's have little fuses that control the interconnects. They minimally need to know the logic units used and how the interconnects connect them which they could reverse engineer from examination of the mask to determine the gates.

      One way to do this is to start with the mask, and create an ASIC with interconnects already in place for the equivalent of a PGA (Programmable Gate Array) without the "P" part. This would still be a "Gate Array" logic part based on the design of the MASK they used but the interconnects would be fixed at the chip creation. This would be about as legal as copying the entire music to a song and replacing the words without paying the songwriter.

      Another way to do this is to create the gates and interconnects as a logical entity (i.e. verilog or other definition language) from the reverse engineering of the mask, then fix variables in the logical entity as constants from the programming data and "simplify" or "reduce" the circuit prior to generation of a custom ASIC.

  4. 'Mask' in this context by Colonel+Panic · · Score: 4, Informative

    The 'mask' in this context can be thought of as a set of transparancies with lines on them that define wires on the chip. Chips are made with a photo-lithography process where light is shined onto silicon through a mask. The lines on the mask block the light from hitting the silicon and depending on the process the areas which are exposed on the silicon will be etched away by acids/solvents. Multiple masks are used to create different features/layers on the silicon. some create wires, others create transistors.

      2) actually clone significant sections of one or more of the FPGA masks themselves into the mask geometry generation step for the automatic ASIC design process, so that the geometry of the FPGA mask is reproduced (perhaps with edits, such as jumpers where programmable transistors would be) in the masks for the ASIC?

    Imagine someone buying one Altera eval board (given away if your company is big enough), designing code, getting the timing all worked out, putting it in a board and then going through all the testing. Voila, working product. Only problem? That FPGA is expensive.

    So, enter clear logic, they'll copy Altera's mask and subtract all the bits that aren't needed. They'll guarantee identical timing, just lower cost and power. Altera is thus shafted out of a sales they need.

While the "underlying ideas" are not necessarily protected, eg. so you could play the exact same notes with very similar timings again on your own instrument, and that would not be considered to be a copyright violation.

Setting the music metaphor aside, if they figured out what the mask has to look like given the verilog code as an in and the resulting data as an out, then that sounds like a clean reverse-engineering. And making a derivative customization of your own workalike mask using the verilog input is just plain clever.

    If I'm reading the article correctly, and the law, and the decision -

    The law in question allows someone to reproduce a photomask /if it's appropriate under IP law to do so/ - It allows them to reverse-engineer a photomask if it's public domain, has been licensed to them, or is owned outright by them - OR if they're trying to figure out how to debug/interface their own code that's being programmed onto an Altera FPGA. It does not seem either of these is the case.

    What Clear Logic seems to have done is get ahold of an Altera FPGA / photomask, and reverse-engineer the programmer portion of the chip - And then made their own device, which translated signals that COULD HAVE been sent to an Altera Field Programmer into the Altera's internal signals to program the Gate Array, and used /those/ signals to lay out their own ASIC.

    Basically, they seem to have hijacked Altera's programming controller (a sizeable chunk of IP) for their own purposes. And probably didn't license it.

    Altera is suitably disturbed because every one of the ASICs Clear Logic makes with their stolen work could have (in theory, anyway) been money in their pocket from licensing the field programmer or could have had their FPGA in place.

    It's as if one has a dynamic web-page generator and backend database, and someone stole the code for that dynamic web page generator & backend database and used it to churn out their own static pages (and sold them) because one's program inherently produces good design.
