JTAG Debug Module Revisions
JTAG Debug Module Revisions
JTAG debug module revisions augment the debug capabilities of the Nios II
processor, or fix bugs isolated within the JTAG debug module logic.

Support for HardCopy devices (previous versions of the JTAG debug module did not
support HardCopy devices).
Bug fix:
When using the Nios II/s and Nios II/f cores, hardware breakpoints may have falsely
triggered when placed on the instruction sequentially following a jmp, trap, or any
branch instruction.
Feature enhancements:
■
(1) Added the ability to trigger based on the instruction address. Uses include
triggering trace control (trace on/off), sequential triggers, and trigger in/out
signal generation.
(2) Enhanced trace collection such that collection can be stopped when the trace
buffer is full without halting the Nios II processor.
(3) Armed triggers – Enhanced trigger logic to support two levels of triggers, or
"armed triggers"; enabling the use of "Event A then event B" trigger definitions.
Bug fixes:
■
(1) On the Nios II/s core, trace data sometimes recorded incorrect addresses
during interrupt processing.
(2) Under certain circumstances, captured trace data appeared to start earlier or
later than the desired trigger location.
(3) During debugging, the processor would hang if a hardware breakpoint and an
interrupt occurred simultaneously.
Initial release of the JTAG debug module.
