`What do you mean by SOC's?
`
`So SOC is an acronym that means
`
`system on a chip.
`
`It's a new flavour of graphic
`
`-- of chips that we do at AMD where everything
`
`from the CPU to the graphic core to multimedia
`
`components is integrated into a single silicon
`
`device to save costs, and area and power.

`
`development is the writing -- in development
`
`starts with the writing of architectural
`
`specifications where architects meet and disc
`
`uSS,
`
`you know,
`
`the various features that are neede
`
`do in
`
`the chip. After specifications are drafted we go
`
`and write C++ code to simulate these
`
`specifications and start understanding the ru
`
`les
`
`and capabilities, and at the same time RTL
`
`developers start to write the register transf
`
`er
`
`layer code for the chip. This code is then
`
`synthesized and turned into what we call gate
`
`level net lists, which are sent to physical
`
`design for place and route, and finally send
`
`Co
`
`Fab's for fabrication.
`
`BY MR. NESE:
`
`Q.
`
`SO you mentioned that there are
`
`there is C++ code for simulation.
`
`Is that ri
`

`
`A.
`
`That is correct.

`

`

`
`MR. TUMINARO: Objection,
`
`form.
`
`THE WITNESS:
`
`Synthesis 18 a process
`
`-- is an automated process by which a tool takes
`
`
`the register transfer layer source code and
`
`transforms it into gates which are, you know,
`
`"and gates", or "or gates" or whatever gates are
`
`available into the physical library that the PD
`
`team will use to fabricate the chip. This flow
`
`is fully automated, and there is no human
`
`intervention needed to go from the RTL to the
`
`gate level simulation.
`
`There is also a formal
`
`validation tool that is provided by the company
`
`
`
`to formally validate
`that does the synthesis tool
`
`that the generated gates are eguivalent to the
`
`RTL code.
`
`

`
`A,
`
`The synthesis time varies based on
`
`the size of each block.
`
`It can go from anywhere
`
`between one hour to 24 hours, depending on really
`
`the size of the design that you are trying to
`
`synthesize.
`
`Q.
`
`And how does a company know that its
`
`RTL code has been synthesized properly?
`
`MR. TUMINARO: Objection,
`
`form.
`
`THE WITNESS: Like I said,
`
`the
`
`company that provides the synthesis tool also
`
`provides a formal equivalence tool that verifies
`
`-- that the generated gates are fully -- formaliy
`
`equivalent to the RTL code.
`
`So after the
`
`synthesis tool is run, we run this tool and, if
`
`any errors or any issues are found,
`
`then the tool
`
`is flagging them and you know, we file a bug to
`
`the company that writes the synthesis tool so
`
`that it can be fixed.
`
`I mean, omce you pass the
`
`formal compliance tool you are guaranteed that
`
`the gates that you generated are equivalent
`
`to
`
`the RTL.

`
`Q.
`
`So if the compliance tool finds a
`
`bug, who fixes it?
`
`Is it the team that wrote the
`
`RTL code, or is it synthesis team,
`
`the validation
`
`team,
`
`the Fab?
`
`A.
`
`So typically the tool will just file
`
`warnings that -- meaning that some gates are --
`
`could be different than what the code really
`
`wanted to do.
`
`So you can go two ways with this.
`
`Once you find one of this,
`
`the RTL code team
`
`could just rewrite the portion of the code that
`
`is problematic in such a way that it's simpler to
`
`synthesize and did not raise this issue. We have
`
`also found issues with the tool itself,
`
`in which
`
`case the company that provides the tool needs to
`
`go and fix the issue in the tool.
`
`QO.
`
`In a typical design process how
`
`often does the validation tool find a bug and
`
`then that requires the RTL team to rewrite some
`
`of the code?
`
`A.
`
`I don't really know how often.
`
`I
`
`know it occurs, but since I was not the person
