Flow Chapter 3. Concepts
Flow
The flow is the set of steps that must be run to complete a design in ACE.
A flow can only be run on an active project implementation, and only on one project’s implementation at a
time during an interactive ACE session.
To run multiple implementations from the same project through the flow simultaneously, use the
Multiprocess View.
To run multiple implementations from separate projects through the flow simultaneously, multiple sessions
of ACE must be run.
Flow Steps
The flow is composed of a series of flow steps, each representing a command operating on the design in the
active implementation. Some flow steps are required (such as preparing the design), and some are optional
(such as writing out a netlist for simulation). Flow steps are generally order-dependent, and running the
steps out of order may result in errors.
The default order flow is displayed in the GUI’s ”Flow view”, with flow steps grouped into categories for
organizational purposes.
Flow Status
Flow steps each have a status associated with them. This status can be seen in the GUI in the ”Flow View”.
Each step can be in one of the following status states:
• Incomplete
• Running
• Complete
• Error
• Disabled
See ”Flow View” for more details.
