Megan WachsandGitHub 338e453a91 JTAG: Use new withClock way of overriding clocks (#1072) 
* JTAG: Use new withClock way of overriding clocks

the override clock way is deprecated

* JTAG: use withClock instead of override clock

* JTAG:  extend Module for ClockedCounter

* JTAG: Don't use deprecated clock constructs

* JTAG: Remove another override_clock

* Rename "NegativeEdgeLatch"

because it's not a latch, it's just a register on the negative edge of the clock.

* Use the appropriately named NegEdgeReg

* JTAG: Rename another NegativeEdgeLatch

Megan Wachs 427b6c9ab8 Emulator: Update it to allow some hard-coded Verilog PlusArgs 2018-01-05 17:08:21 -08:00
Megan Wachs 76c5fd0c0c travis: Use newer infrastructure, but require sudo for additional disk space. 
This is because as of Dec 12, 2017, Travis changed their container images and seem
to give slightly less disk space. Using a sudo image gives more disk space.
 2018-01-05 17:08:21 -08:00
Megan Wachs e6661a6982 Debug regressions: use a plusarg to enable remote bitbang. 2018-01-05 17:08:21 -08:00

Megan Wachs 9df3604007 emulator: No reason not to emit waveforms during reset 2018-01-05 17:08:21 -08:00
Megan Wachs 024cd52c44 debug: attempt to make the simulation deterministic by not returning until connection is made and command is receieved 2018-01-05 17:08:21 -08:00
Megan Wachs 1d3fa07c44 debug: print failures when debug tests fail, so we can see why it is failing on Travis 
Cleanups, and print out log names ASAP.

Factor out gdbserver common invocation into GDBSERVER (fixing
--print-failtures).
Add --print-log-names to that command so the logfiles can be inspected
while the simulation is still running.
`RISCV=... cmd` is more idiomatic than `export RISCV=... && cmd`

Megan Wachs e82328336e Add in a SimJTAG to connect to OpenOCD's remote-bitbang interface. 
This is simpler than JTAGVPI and is supported better by Verilor.
It is also the same thing Spike uses.
