Class Method Details

.configuration {|@config| ... } ⇒ Object

Accessor for the global LSF configuration, use this to modify the default LSF configuration for a given setup. Typically an alternate configuration would be added to the SoC class or the target file, but it can be set from anywhere. This method returns an instance of Origen::Application::LSF::Configuration and can be used as shown in the example.

Example

# soc/nevis.rb

ORIGEN::Runner::LSF.configuration do |config|
# Use "msg.nevis" for the project string when running in Noida
if %x["domainname"] =~ /nidc/
  Origen.config.lsf.project =  "msg.nevis"
end
# Change the default group
Origen.config.lsf.group = "lam"

Yields:
