Why emulation performance doesn’t matter (on its own)

Emulation performance is a key metric in verification. But it is far from being the only consideration. How long it takes to get a design onto a verification platform and aspects such as debug are as important. These factors will control how verification platforms are deployed during a project's life cycle.

Early tape-out: smart verification or expensive mistake?

Is it worth trying to iron out all the bugs in an SoC before taping out, or should design teams anticipating a re-spin go to silicon earlier and use the chips that come back as verification accelerators?

X propagation

X propagation within RTL simulations can hide fatal bugs. Uncovering and eliminating the effect improves design quality and avoids respins.

Symbolic simulation speeds timing closure

Timing closure is a key challenge for today’s complex system-on-chip designs. Static timing analysis (STA) tools automatically analyze signal paths in a design and identify timing-critical paths that limit the clock frequency that can be achieved. Paths that can never be functionally activated or that require multiple cycles for correct operation can be identified as [...]

Device native debug and verification for FPGA

GateRocket's RocketDrive facilitates integration of an FPGA into an HDL simulator to provide a "native" execution of a design on its target FPGA device. The companion RocketVision tool provides software-debugging capabilities that directly identify and enable the rapid resolution of bugs. This article considers the use of these tools in a "device native" verification and [...]

Advanced RTL power-aware verification

Traditional verification tools struggle to deal with today’s increasingly sophisticated power management technologies. One major limitation is that they cannot deal with varying power states because they make a built-in assumption that devices are always fully powered on. Further, power-aware verification at the register-transfer level is proving increasingly problematic, although it is also becoming increasingly […]
