June, 2013 ASSET Enhances IJTAG Embedded Tool
Richardson, TX — ASSET® InterTech’s Scan- Works® IJTAG Test tool has been given improve- ments for its graphical viewer and now has signif- icantly faster performance. These enhancements allow engineers to access, control and automate the operations of test and measurement instru- ments embedded in chips. ScanWorks IJTAG Test was the first suite of
tools supporting the new IEEE P1687 Internal JTAG (IJTAG) standard for embedded instrumen- tation. IJTAG gives chip designers a more effective method for debugging chip designs by standardiz- ing the way engineers control and access the in- struments they have embedded on-chip. In addi- tion, these same embedded instruments can be re- applied later to test, validate and debug prototypes of circuit board designs and manufactured boards. Users of ScanWorks IJTAG Test have de- ployed the tool in a variety of applications. Some
are validating IJTAG structures that have been in- tegrated into SoCs and application-specific inte- grated circuits (ASIC). Others have implemented
the tool in prototype circuit board bring-up and in board manufacturing itself. One user is employing ScanWorks IJTAG Test to access embedded in- struments by way of IJTAG and other on-chip structures, such as those specified in the IEEE 1500 standard for embedded core test. ScanWorks IJTAG Test tools can read
ScanWorks IJTAG Test’s instrument map.
IJTAG’s two languages — Instrument Connectivi- ty Language (ICL) and Procedural Description Language (PDL). ICL defines the access connec- tions for the instruments embedded on-chip while PDL is an extension of the popular Tcl (Tool Com- mand Language) for programming validation, test and debug vectors to be executed by embedded IJTAG instruments. With the graphical user inter- face on ScanWorks IJTAG test engineers can drag- and-drop instruments and specific operations to automatically develop test routines. The IJTAG standard recently passed a signifi- cant milestone on the road to ap- proval. In advance of its going to bal- lot, the draft of the specification has been submitted to the IEEE’s Mandatory Editorial Coordination (MEC) process, which determines whether the draft of the specification conforms to the IEEE’s editorial re- quirements. Following the MEC re- view, IEEE balloting to ratify the
IJTAG standard can begin. Contact: Asset InterTech,

WonderMASK PX New from Techspray
Amarillo, TX — Techspray has in- troduced what the company de- scribes as the fastest ambient cured mask on the market — Wonder- MASK® PX.
WonderMASK PX is a tempo-
rary, peelable, latex solder mask de- signed to dry in half the time of other solder masks. It is hand-ap- plied and can withstand fluxing, wave soldering and cleaning opera-
Fast-dry high-strength mask.
tions. It effectively masks and pro- tects open through-holes and un- derside components in wave solder- ing processes, withstanding tem- peratures up to 650°F (343°C), and can be used as a conformal coatings mask. The material has good tensile strength when fully cured, so it peels easily and is excellent when a thick coat of mask is required. WonderMASK PX has been
specially formulated to cure homo- geneously throughout, which avoids the headache of a thick bead of
mask with an uncured center. Contact: Techspray, P.O. Box
