Running the Flow Chapter 4. Tasks

and ACE is still unable to successfully submit jobs to the GridEngine, please contact Achronix technical

support.

WARNING:

Attempting to manually run the logged qsub command (without

the Multiprocess View’s additional automated safety locks in place)

may cause ACE dataﬁle corruption. While ACE does provide the

complete attempted qsub command in the ”Multiprocess Run Logs”

section of the Multiprocess view, DO NOT copy the text of the

attempted command and manually attempt execution from the

command-line. A large number of assumptions are made (including

bypassing the normal project-level and implementation-level safety

checks which prohibit ﬁle corruption) when ACE is executed using

the provided command options and Tcl batch script these

assumptions are violated during manual execution attempts.

Conﬁguring the Desired Flow to be Followed by the Selected Implementations

All the implementations run through the Multiprocess View will follow the same ﬂow steps through the

ﬂow, as conﬁgured in the Flow View. Thus, users must ensure all optional ﬂow steps are enabled/disabled

as desired before starting multiprocess execution.

Additionally, in the section of the Multiprocess View labeled ”Multiprocess Flow Management”, users may

choose to stop the multiprocess ﬂows early, prior to traditional ”completion”. (For example, when designs

are known to be incomplete, and thus known to fail the Run Final DRC Checks ﬂow step, users may choose

to stop the ﬂow prior to running that ﬂow step.)

To stop all the multiprocess ﬂows at a given ﬂow step, simply select that ﬂow step in the Stop Flow After:

drop-down list. No subsequent ﬂow steps will be executed for the selected multiprocess implementations.

As a convenience, since optional ﬂow steps are frequently chosen to be the ﬁnal multiprocess ﬂow step,

there is a Force Selected Flow Step to be Enabled checkbox. When checked, if the selected ﬁnal ﬂow step

is optional and not enabled, then as the multiprocess implementations are scheduled, the selected ﬂow step

is enabled for all the multiprocess implementations before they begin execution. If this checkbox is left

unchecked, and a disabled optional ﬂow step is selected as the ﬁnal step, then the ﬁnal step executed will

be the last enabled ﬂow step prior to the selected step.

For example, if Stop Flow After is set to Run Post-Route Timing Analysis (an optional step), but this ﬂow

step is disabled in the Flow View, and if Force Selected Flow Step to be Enabled is not checked, then the

multiprocess ﬂows will stop after the (required) Run Route ﬂow step

, since that is the last enabled step

prior to Run Post-Route Timing Analysis.

Selecting the Implementations to be Run in Parallel

In the Projects View, select the desired project. The Implementation Table within the Multiprocess view’s

”Select Implementations” section will be updated to display data for the active project and implementation.

In the Multiprocess View, ensure the Existing Implementations radio button within the ”Select

Implementations” section is selected. This will limit the contents of the Implementation Table to just the

implementations which already exist for the active project. (Generating and executing new implementations

using option sets is covered in Attempting Likely Optimizations Using Option Sets.)

In the Implementation Table, all listed implementations will be selected (the checkbox in the Implementation

column will be checked) by default. Implementations may be selected/deselected in bulk with the Select

All and Deselect All buttons. Individual implementations may have their selection toggled by clicking

their checkboxes in the ﬁrst column of the Implementation Table.

they may stop sooner, if they encounter errors
