Parametric Functionality

Parametric Functionality#

One of the main benefits of open-source electronics is the ability to explore parametric designs closely interfaced with existing design flows in common languages, far more than writing old archaic tool-specific scripting languages.

OpenLane Parametric Parameters#

A list of interesting OpenLane design parameters over which you might want to parametrise your design could be:

Parameter

Description

CLOCK_PERIOD

in nanoseconds

PL_TARGET_DENSITY

SYNTH_PARAMETERS

yosys synthesis parameters for parametric designs

SYNTH_CAP_LOAD

The capacitive load on the output ports in femtofarads.

SYNTH_MAX_FANOUT
