3.1. Hammer CAD Tools
Hammer currently has open-source CAD tool plugins in the hammer/<action>
folders and three repos for CAD tools from commercial vendors: hammer-cadence-plugins
, hammer-synopsys-plugins
, and hammer-mentor-plugins
. hammer-mentor-plugins
is a private repo since it contains tool-specific commands not yet cleared for public release. Access to them may be granted for Hammer users who already have licenses for those tools. See the note about plugins access for instructions for how to request access.
The structure of each repository is as follows:
hammer
ACTION
TOOL_NAME
__init__.py
contains the methods needed to implement the tooldefaults.yml
contains the default Hammer IR and Meta Variables needed by the tool
ACTION is the Hammer action name (e.g. par
, synthesis
, drc
, etc.).
TOOL_NAME is the name of the tool, which is referenced in your configuration.
For example, if ACTION is par
and TOOL_NAME is par_tool_foo
, the configuration would reference it as hammer.par.par_tool_foo
.
