Making SoCs Easier to Debug

A New Technology Aims to Track Both Software and Hardware Bugs

by Dick Selwood

System debugging used to be fairly straightforward. Components were on a board, linked by tracks, and, with a 'scope and probes, you could look at signals and work out what was happening. Of course it didn't seem so simple at the time - isn't hindsight great? In time, systems got more complex, microcontrollers got more complex, and the companies building ‘scopes and other tools for hardware debugging came up with more and more sophisticated (which implies expensive) products. Digital 'scopes, logic analysers and emulators all helped engineers in their efforts to keep up. JTAG was created to provide an interface - now frequently to a PC as well as to specialist tools - as multilayer boards hid tracks, and it was then used to provide visibility of operations within the chip. The JTAG interface is now also used for software debugging, as through JTAG it is possible to control program execution, stepping through line by line, or to set breakpoints. JTAG can also be used to program flash memory. Processor manufacturers started fairly early on to provide proprietary analysis tools, and ARM, for example, provides a range of interfaces and on-chip capabilities for advanced debugging and analysis.  Read More

Rumors Intel Altera Deal is Close

posted by Kevin Morris

The NY Post reported today that sources told them that an Intel/Altera deal was close, and could be done by the end of next week. At the same time, we are hearing from multiple Altera customers who are opposed to the deal. (28-May)

Intel/Altera Agreement (Partially) Tells the Tale

posted by Kevin Morris

We did a lot of speculation in our recent articles about the rumored Intel bid to buy Altera. One of the areas of most intense speculation was the 2013 agreement the two companies signed - for Intel to manufacture 14nm FPGAs for Altera. More than two years after that deal was signed, Intel is rumored to be making an offer to buy Altera for upwards (maybe far upwards) of $10B. But, is the existing 2013 agreement potentially weakening Intel’s bargaining position? (4-May)

Intel Buying Altera? We Totally Called It.

posted by Kevin Morris

Rumors abound today that Intel is in negotiations to buy Altera - a deal that could be worth over ten billion. If so, it would be the largest acquisition in Intel's history. We have no confirmation from either company that such a deal is in play, but we did a pretty thorough analysis of the situation last June in this article: What do you think? (27-Mar)
