-# groundtest
-
-A memory tester circuit for Rocket Chip's memory system. The generator tile
-plugs into the existing SoC generator as what looks like a CPU. However,
-instead of running programs, the tile generates fixed memory requests out to
-the L2. There are both cached and uncached generators. The cached generator
-has an intervening L1 cache, the uncached generator sends TileLink requests
-directly to the L2.
-
-Assertions are set to fail if the wrong data comes back or if a request times
-out waiting for the response.
-
-## Configuring Rocket-Chip with groundtest
-
-The groundtest package defines a GroundTestTile, which extends a
-rocket-chip Tile.  A number of Configs in rocket-chip instantiate
-GroundTestTile(s) in place of other types of Tiles (see
-[TestConfigs.scala](https://github.com/ucb-bar/rocket-chip/blob/master/src/main/scala/TestConfigs.scala)).
-
-Running a ground test can be achieved in rocket-chip as follows
-(assuming the `build.sh` script in the
-`rocket-chip/riscv-tools` directory has already been run).
-
-```
-cd emulator
-make CONFIG=<GroundTestConfigName>
-ln -s ../riscv-tools/riscv-tests/build/isa/rv64ui-p-simple
-./emulator-Top-<GroundTestConfigName> rv64ui-p-simple <other args>
-```
-
-Currently the Configs which include GroundTestTile(s) are:
-
-- MemtestConfig
-- MemtestL2Config
-- BroadcastRegressionTestConfig
-- CacheRegressionTestConfig
-- UnitTestConfig
-- TraceGenConfig
-- ComparatorConfig
-- ComparatorL2Config
-
-The usual Make targets run-asm-tests and run-bmark-tests still work for these configurations, though they don't do much.
-
-## Using TraceGenConfig
-
-The trace generator in groundtest
-([tracegen.scala](https://github.com/ucb-bar/groundtest/blob/master/src/main/scala/tracegen.scala)) has the ability to generate random memory-subsystem traces, i.e. random sequences of memory requests, along with their responses. The idea is that these traces can be validated by an external checker, such as [axe](https://github.com/CTSRD-CHERI/axe).
-
-Putting the generator and the checker together, we can automatically search for invalid traces, i.e. possible bugs in the memory subsystem. This is useful for intensive testing, but also debugging: it is possible to search for simple failing cases.
-
-### Quick Reference
-
-The [tracegen+check.sh](https://github.com/ucb-bar/groundtest/blob/master/scripts/tracegen%2Bcheck.sh) script provides an automated way to run a number of randomized tests. The number of tests, initial seed, and other parameters can be set via environment variables or the command line, see the script for more details. 
-
-Before running the script, first ensure that:
-
-- the file `rocket-chip/riscv-tools/riscv-tests/build/isa/rv64ui-p-simple`
-  exists (this is produced by the `build.sh` script in the
-  `rocket-chip/riscv-tools` directory);
-- `rocket-chip/groundtest/scripts` in your `PATH`;
-- `rocket-chip/emulator` is your current working directory.
-
-Now the script can be run as follows.
-
-```
-> make CONFIG=TraceGenConfig
-> tracegen+check.sh
-Testing against WMO model:
- 
-       0: .......... .......... .......... .......... .......... 
-      50: .......... .......... .......... .......... ..........
-
-OK, passed 100 tests
-LR/SC success rate: 88%
-Load-external rate: 45%
-```
-
-### Running Manually
-
-Suppose we have built the Rocket Chip emulator with the TraceGenConfig
-configuration as above. Running it using the
-[tracegen.py](https://github.com/ucb-bar/groundtest/blob/master/scripts/tracegen.py)
-wrapper script with a few command-line options gives us a random
-trace:
-
-```
-  > tracegen.py ./emulator-Top-TraceGenConfig 1 rv64ui-p-simple
-  1: load-req     0x0000000008 #0 @64
-  1: store-req  5 0x0000100008 #1 @65
-  1: store-req  7 0x0000000010 #2 @66
-  0: store-req  2 0x0000000008 #0 @303
-  0: load-req     0x0000000008 #1 @304
-  0: store-req  6 0x0000100008 #2 @305
-  1: resp       0              #0 @96
-  0: resp       0              #0 @350
-  0: resp       2              #1 @351
-  0: load-req     0x0000000010 #3 @353
-  1: resp       0              #1 @149
-  1: load-req     0x0000000108 #3 @152
-  1: resp       0              #3 @184
-  0: resp       5              #2 @422
-  0: resp       0              #3 @424
-  1: resp       0              #2 @226
-  ...
-```
-
-Main points:
-
-- the second command-line option sets the random seed;
-- the first number on each line of the trace is the core id;
-- \#N denotes a request-id N;
-- @T denotes a time T in clock cycles;
-- hex numbers denote addresses;
-- remaining decimal numbers denote values being loaded or stored;
-- the value written by every store is unique (this simplifies trace checking and reasoning);
-- this trace contains only loads, stores and responses, but the generator (and axe) also support LR/SC pairs, atomics, and fences.
-
-
-We convert these traces to axe format using the
-[toaxe.py](https://github.com/ucb-bar/groundtest/blob/master/scripts/toaxe.py) script.
-
-```
-  > tracegen.py ./emulator-Top-TraceGenConfig 1 rv64ui-p-simple | toaxe.py -
-  # &M[2] == 0x0000000010
-  # &M[0] == 0x0000000008
-  # &M[3] == 0x0000000108
-  # &M[1] == 0x0000100008
-  1: M[0] == 0 @ 64:96
-  1: M[1] := 5 @ 65:
-  1: M[2] := 7 @ 66:
-  0: M[0] := 2 @ 303:
-  0: M[0] == 2 @ 304:351
-  0: M[1] := 6 @ 305:
-  0: M[2] == 0 @ 353:424
-  1: M[3] == 0 @ 152:184
-  ...
-```
-
-Main points:
-
-- lines begining # are comments, showing the addresses being used;
-- after @ are the optional begin and end times of the operation.
-
-Axe traces can be validated using the [axe](https://github.com/CTSRD-CHERI/axe) tool (must be downloaded and installed seperately):
-```
-> tracegen.py ./emulator-Top-TraceGenConfig 1 rv64ui-p-simple | toaxe.py - | axe check WMO -
-OK
-```
-
-Axe reports that this trace is valid according to the WMO model.

-Rocket Core
-===========
-
-Rocket is a 6-stage single-issue in-order pipeline that executes the 64-bit
-scalar RISC-V ISA.  Rocket implements an MMU that supports page-based virtual
-memory and is able to boot modern operating systems such as Linux.  Rocket
-also has an optional IEEE 754-2008-compliant FPU, which implements both
-single- and double-precision floating-point operations, including fused
-multiply-add.
-
-This repository is not intended to be a self-running repository. To
-instantiate a Rocket core, please use the Rocket chip generator found in the
-rocket-chip git repository.
-
-The following table compares a 32-bit ARM Cortex-A5 core to a 64-bit RISC-V
-Rocket core built in the same TSMC process (40GPLUS). Fourth column is the
-ratio of RISC-V Rocket to ARM Cortex-A5. Both use single-instruction-issue,
-in-order pipelines, yet the RISC-V core is faster, smaller, and uses less
-power.
-
-ISA/Implementation | ARM Cortex-A5 | RISC-V Rocket | R/A
---- | --- | --- | ---
-ISA Register Width | 32 bits | 64 bits | 2
