Which Verification Engine?


Semiconductor Engineering sat down to discuss the state of verification with Jean-Marie Brunet, senior director of marketing for emulation at [getentity id="22017" e_name="Mentor, a Siemens Business"]; Frank Schirrmeister, senior group director for product management at [getentity id="22032" e_name="Cadence"]; Dave Kelf, vice president of marketing at [getentity id="22395" e_name="OneSpin Solut... » read more

Prototypes Proliferate


Hardware prototyping and [getkc id="30" kc_name="emulation"] have been two sides of the same coin ever since the [gettech id="31071" comment="FPGA"] became a commercial success. Early emulators were all built from FPGAs, and most were used in-circuit, much like prototypes are today. More recently, emulation has become a major piece of the [getkc id="10" kc_name="verification"] flow, to the poin... » read more

System Coverage Undefined


When is a design ready to be taped out? That has been one of the toughest questions to confront every design team, and it's the one verification engineers lose sleep over. Exhaustive [getkc id="56" kc_name="coverage"] has not been possible since the 1980s. Several metrics and methodologies have been defined to help answer the question and to raise confidence that important aspects of a block... » read more

Making Software Development Equivalent For Models And Boards


Selected Cortex-M processors include the instruction trace microcell (ITM) to help understand system behavior. Although it can provide other types of trace, the ITM is commonly associated with printf() output and event tracing from applications and operating systems. Historically, Fast Model systems have used semihosting or UART models to provide character and file I/O when running software on ... » read more

Verification’s Breaking Points


Verification efficiency and speed can vary significantly from one design to the next, and that variability is rising alongside growing design complexity. The result is a new level of unpredictability about how much it will cost to complete the verification process, whether it will meet narrow market windows, and whether quality will be traded off to get a chip out on time in the hopes that it c... » read more

When Is Verification Complete?


Deciding when verification is done is becoming a much more difficult decision, prompting verification teams to increasingly rely on metrics rather than just the tests listed in the verification plan. This trend has been underway for the past couple of process nodes, but it takes time to spot trends and determine whether they are real or just aberrations. The Wilson Research Group conducts a ... » read more

When A Lot May Not Be Enough


For the last couple of months my son has been trying to save for a Nintendo Switch. The emphasis here is on “trying to.” The problem is that whenever he amasses enough money to buy something else, he tends to spend the money on a cheaper toy like a new Lego Dimensions figure. I guess that delayed gratification isn’t really a strength of my son. His assumption is that the best way to colle... » read more

How Much Verification Is Necessary?


Since the advent of IC design flows, starting with RTL descriptions in languages like Verilog or VHDL, project teams have struggled with how much verification can and should be performed by the original RTL developers. Constrained-random methods based on high-level languages such as [gettech id="31021" t_name="e"] or [gettech id="31023" comment="SystemVerilog"] further cemented the role of t... » read more

Hybrid Emulation


Semiconductor Engineering sat down to discuss the growing usage of hybrid verification approaches with Frank Schirrmeister, senior group director of product management & marketing for [getentity id="22032" e_name="Cadence"]; Russ Klein, program director for pre-silicon debug products at [getentity id="22017" e_name="Mentor, a Siemens Business"]; [getperson id="11027" comment="Phil Moorby"],... » read more
