jtag

JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs and testing printed circuit boards after manufacture.
JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. It specifies the use of a dedicated debug port implementing a serial communications interface for low-overhead access without requiring direct external access to the system address and data buses. The interface connects to an on-chip Test Access Port (TAP) that implements a stateful protocol to access a set of test registers that present chip logic levels and device capabilities of various parts.
The Joint Test Action Group formed in 1985 to develop a method of verifying designs and testing printed circuit boards after manufacture. In 1990 the Institute of Electrical and Electronics Engineers codified the results of the effort in IEEE Standard 1149.1-1990, entitled Standard Test Access Port and Boundary-Scan Architecture.
The JTAG standards have been extended by many semiconductor chip manufacturers with specialized variants to provide vendor-specific features.

Did you know?

Credit is the trust which allows one party to provide money or resources to another party wherein the second party does not reimburse the first party immediately, but promises either to repay or return those resources at a later date.

Lenders want to make sure all their bases are covered before they extend you credit. That means they may look at factors other than your credit score to determine whether to lend you money. Your employment status also can play a role: If your income is too low or you haven’t been at your current workplace long, those factors could weigh against you.

Errors can come in a variety of forms. You may not have been credited for a payment you made, or you may have been charged for a purchase you didn’t make. A debt might be listed more than once, or your balance might be wrong.
