Next we need to generate a DUT wrapper. We provide two pre-written wrappers, you can also build new DUT wrappers.
Please see https://github.com/OpenXiangShan/HuanCun/blob/non-inclusive/src/test/scala/huancun/TestTop.scala for more information.
> make test-top-l2 // For StandAlone L2 test
> make test-top-l2l3 // For L2-L3 test
> git clone https://github.com/OpenXiangShan/tl-test.git
> mkdir build
> cd build
> cmake .. -DDUT_DIR=${PATH_TO_HUANCUN}/build
For trace-dump, add -DTRACE=1
For multi-thread, add -DTHREAD=${NR_THREADS}
For tllog-dump, add -DTLLOG=1
Please read [# Use TLLog] beneath for more infomation.
> make
> ./tlc_test
-s --seed=N Set N as random seed
-c --cycle=N Simulate for N cycles
-b --wave-begin=N Wave dump starts from cycle N
-e --wave-end=N Wave dump ends to cycle N
-f --wave-full Dump wave in full cycles
-v --verbose Verbose mode
--dump-db Dump tllog database file
Please check -DTRACE=1 is added to tl-test compiling cmake arguments before wave dump.
Please check -DTLLOG=1 is added to tl-test compiling cmake arguments before dump tllog database, see [# Use TLLog] for more infomation.
Tl-test will dump wave to directory tl-test/build/ if wave_begin < wave_end.
TLLog is a method that can capture messages on TileLink bus, which may be helpful for debugging. To use TLLog:
Make sure that your HuanCun has huancun.utils.ChiselDB(e.g. HuanCun on branch 'nanhu-chiseldb').
Make sure that SQlite3 has been installed in your machine.
Build HuanCun and clone tl-test following above steps.
> cmake .. -DDUT_DIR=${PATH_TO_HUANCUN}/build -DTLLOG=1
> make
> ./tlc_test --dump-db
The .db file will write to tl-test/build.
*Attention: it won't save the .db file until the tl-test program ends.
Use the following commands to open .db file:
> sqlite3 <database.db> "SELECT * FROM TLLOG"
To filter the table by a specific table entry:
> sqlite3 <database.db> "SELECT * FROM TLLOG WHERE <ENTRY>=<VALUE>"
e.g.
- see all messages between L1D_0 and L2:
> sqlite3 <database.db> "SELECT * FROM TLLOG WHERE SITE='L1D_L2_0'"
- see all messages on channel A
> sqlite3 <database.db> "SELECT * FROM TLLOG WHERE CHANNEL='0'"
** There is a script in tl-test/script, which help you get better experience on reading the database file: **
> sqlite3 <database.db> "SELECT * FROM TLLOG" | sh script/convert_tllog.sh
