We know that the board bring-up process can be extremely challenging on today’s complex, high-speed designs. How do we get the iterative validation, test and debug steps off of the critical path of new product introduction?

A customer shared some empirical results from boundary-scan testing of the Intel QuickPath Interconnect (QPI) nets on their design. These nets cannot be covered using In-Circuit Test (ICT), and some short-circuit and open-circuit defects defy detection using conventional functional test. What did they find?

Boundary scan is known to be quite slow to program large flash devices. But, with a new approach using SPI Master IP within an FPGA, flash programming time can be decreased by a factor of 15 or more.

In previous blogs, we contrasted the use of oscilloscopes to perform signal integrity validation (SIV) against silicon embedded instruments for system marginality validation (SMV). Why is SMV superior?

Let’s say you wanted to debug a CATERR on an Intel x86-based system out in the field. And let’s say that the CATERR only happened in a given datacenter once a week. An embedded implementation of the In-Target Probe (ITP) would help.
