TBRUN(1) Retro Project Manual TBRUN(1) NAME tbrun - test bench driver SYNOPSIS tbrun [OPTION]... [DSCFILE] DESCRIPTION tbrun organizes the execution of large sets of test benches. It will - read the file DSCFILE, which describes the full set of test benches. The top-level DSCFILE typically includes other files which allow organizing the description in a well-structured manner. If no DSCFILE is specified the file tbrun.yml in the current work- ing directory is used. - select based on the given --tag and --exclude options the tests to be executed in a given run. - determine based on the --mode option the simulation engine and the simulation type, behavioral or post-synthesis or later. See section MODES for details. - execute the tests which as much parallelism as possible. The --jobs option specifies the maximal number of jobs and a locking logic prevents more than one test from running in a working directory. OPTIONS --tag=tlist specifies the tags a test must match to be selected for execu- tion. tlist can be a comma-separated list of tags, a test must match all tags given in tlist to be selected. --tag can be specified multiple times and the selections are ored. In effect, a test must match all tags in the tlist of one of the specified --tag options. If no --tag option is given an implicit --tag=default is as- sumed, so all tests with the tag 'default' are executed. --exclude=tlist specifies the tags a test must not match. tlist can again be a comma-separated list, a test that matches all the tags given is excluded. --exclude can be specified multiple times and the rejections are ored. In effect, a test is rejected if it matches all tags in the tlist of one of the specified --exclude options. --all is simply a shortcut for --tag=".*" and selects all tags. Can be combined with --exclude but not with other --tag options. --mode=mlist determines the simulation engine and the type of simulation. Can be a comma-separated list, if several modes are specified all of them will be executed. If no --mode is given the default value 'bsim' is used. Note that unlike --tag and --exclude only a single --mode option is processed, if multiple are present only the last one will be used. Each mode specification has the format '[engine]_[type]' and follows the model name suffix rules of the build system. If the engine part is omitted ghdl(1) is assumed as the default. If the type part is omitted 'bsim' is assumed as default. Other supported values for engine are ISim the Xilinx ISE build-in simulator XSim the Xilinx Vivado build-in simulator The type part has the following supported values bsim behavioral simulation ssim post-synthesis functional simulation fsim post-map simulation (only ISE) osim post-optimize functional simulation (only Vivado) rsim post-routing functional simulation (only Vivado) esim post-synthesis timing simulation (only Vivado) psim post-optimize timing simulation (only Vivado) tsim post-routing timing simulation --jobs=njob specifies the maximal number of parallel jobs. Without the --jobs option the tests are executed sequentially and the test output is forwarded immediately to stdout. With the --jobs option a task dispatcher is used which starts the jobs, received and buffers the test output, and forwards it to stdout when the job completes. The test outputs are always in the original selection order, thus not affected by the comple- tion order. The task dispatcher displays also a progress line when stdout is a terminal device of the format #-I: t047: 5l 35.6s; t053: 5l 20.2s (26t,2w,31o) where t***: specifies the current task number **l number of output lines collected for this task *.*s run time (as real time) of the task (running since time) **t number of tasks still waiting for execution *w number of tasks currently running *o number of tasks in the pending output queue Note that --jobs enables the task dispatcher and thus output buffering and progress line output even when njob is '1' ! --tee=outfile if specified all output send to stdout except for the progress line updates is also written in the file outfile. This is very convenient in conjunction with the --jobs option which generates progress line output only when stdout is a terminal device. Us- ing shell pipes and tee(1) will therefore prevent progress lines, use the --tee instead to save the output into a file. --list list selected tags and quit. --dry dry run, prints the generated commands, but doesn't execute. When used without the --jobs option a commented list of shell commands is printed which describes the linear execution of the selected tests. When used together with --jobs this option mainly serves to de- bug the task dispatcher. A random wait of 0.2 to 1.8 sec is gen- erated for each selected test. --trace prints additional information on job control. --nomake don't execute make step of the test bench. Will be forwarded to tbrun_tbw(1) and tbrun_tbwrri(1) based test benches. --norun don't execute run step of the test bench, useful to only execute make step. Will be forwarded to tbrun_tbw(1) and tbrun_tb- wrri(1) based test benches. --rlmon enable the rlink monitor, will be forwarded to tbrun_tbwrri(1) based test benches. --rbmon enable the rbus monitor, will be forwarded to tbrun_tbwrri(1) based test benches. --bwait=twait specifies startup wait for behavioral simulations. twait must be an integer, the time unit is 1 ns. Will be forwarded to tbrun_tbwrri(1)-based test benches. --swait=twait specifies startup wait for post-synthesis and higher simula- tions. twait must be an integer, the time unit is 1 ns. Will be forwarded to tbrun_tbwrri(1)-based test benches. --help print short help text. EXIT STATUS In case of an error, the exit codes are: 1 run time errors, like a bad option, file not found, etc 2 at least one test FAILed, test bench has FAILed ENVIRONMENT TBW_GHDL_OPTS Used by tbw(1) to define additional options for ghdl-based simula- tions. Usually set to "--unbuffered --ieee-asserts=disable-at-0", see tbw(1) documentation. EXAMPLES tbrun The simplest default case, will use the tbrun.yml file in the cur- rent working directory, assume --tag=default, and --mode=bsim. This selects all tests tagged with 'default' and runs the behav- ioral simulation with ghdl(1). Done in simple sequential mode. tbrun --jobs=2 --tag=viv,sys_w11a --mode=XSim Will select all tests which have a 'viv' and a 'sys_w11a' tag, use XSim as the simulation engine and run the behavioral simulation. Will use the task dispatcher and will try to run 2 tests in paral- lel. SEE ALSO tbrun_tbw(1), tbrun_tbwrri(1), tbfilt(1) AUTHOR Walter F.J.
