Background Execution of Reporting Commands in Cadence Genus
Cadence Genus supports doing report in parallel and running them in the background with run_parallel_commands.
Number of parallel processes depends on the
max_cpu_per_server setting.
Supported commands: report*, write*, check_timing_intent.
This tutorial introduces how to conditional enable this feature by adding a conditional prefix to the supported commands.
Step 1: query Genus version
Get the Genus version using get_db program_major_version, which will be used for condition.
set genus_version [get_db program_major_version]
Step 2: set conditional command
Set a conditional string that if supports run_parallel_commands, then it is the prefix of supported commands. Otherwise, the prefix is null.
if { $genus_version >= 21 } {
set parallel_cmd "run_parallel_commands -log_dir $LOG_PATH -queue "
} else {
set parallel_cmd {}
}
Step 3: add a prefix to the supported commands.
Using the following syntax to add the command to a queue.
"${parallel_cmd}\"YOUR CMD\""
# e.g.
"${parallel_cmd}\"report_timing\""
Step 4: execute the commands in the queue
After adding all the commands within one stage, you have to execute them parallelly using run_parallel_commands -execute.
if {$genus_version >= 21 }{
run_parallel_commands -execute
}
Summary
set genus_version [get_db program_major_version]
if { $genus_version >= 21 } {
set parallel_cmd "run_parallel_commands -log_dir $LOG_PATH -queue "
} else {
set parallel_cmd {}
}
"${parallel_cmd}\"YOUR CMD\""
if {$genus_version >= 21 }{
run_parallel_commands -execute
}
