Flowkit run_syn_generic returned successfully but encountered errors (TIM-306; SDC-202)

Achim Vandierendonck

While testing out the flowkit, I noticed that, using a rather basic flow, I could successfully run up to (but not including) run_syn_generic.
When running run_syn_generic it tool reports two errors have occurred:

------------------------------------
$ flowtool -directory build/flowkit -to syn_generic.run_syn_generic -reset
Flowtool

Command: -directory build/flowkit -to syn_generic.run_syn_generic -reset
Script: scripts/flow.yaml
Version: v21.10-d038_1, built 02/12/2021 04:34 PST

flow_current @ genus: synthesis.syn_generic.block_start -> synthesis.syn_generic.run_syn_generic returned successfully but encountered errors
log file:
build/flowkit/logs/syn_generic.block_start-run_syn_generic.log
error summary:
Severity ID Count Step Where Summary
ERROR message:TIM/TIM-306 1 synthesis.syn_generic.run_syn_generic .body_tcl line 3 Unspecified analysis view.
ERROR message:SDC/SDC-202 1 synthesis.syn_generic.run_syn_generic .body_tcl line 3 Could not interpret SDC command.

Flow ran to completion
------------------------------------

The verbose option does not shed more light on the issue as no error is generated in the verbose log, but the tool still reports the error.

However, when I run the flow in interactive mode up to the step before run_syn_generic (which is create_cost_group) using:

flowtool -directory build/flowkit -to syn_generic.create_cost_group -reset -interactive_run

and manually perform syn_generic, then it does not return an error.

I cannot seem to locate the log file, nor the command that causes the error. I have no idea where .body_tcl line 3 is as that body only contains two lines:

------------------------------------
##############################################################################
# STEP run_syn_generic
##############################################################################
create_flow_step -name run_syn_generic -owner cadence {
  #- Synthesize to generic gates
  syn_generic
}
------------------------------------
Is there a way to figure out why and where the error originates and how to fix it?
