JAM / STAPL ("Standard Test and Programming Language") is an
Altera-developed standard for
JTAG
JTAG (named after the Joint Test Action Group which codified it) is an Technical standard, industry standard for verifying designs and testing printed circuit boards after manufacture.
JTAG implements standards for on-chip instrumentation in ele ...
in-circuit programming of
programmable logic devices which is defined by JEDEC standard JESD-71.
STAPL defines a standard ''.jam'' file format which supports in-system programmability or configuration of programmable devices.
A JTAG device programmer implements a ''JAM player'' which reads the file as a set of instructions directing it to program a
PLD.
The standard is supported by multiple PLD and device programmer manufacturers.
