Unable to complete flow2 with Flow/Nangate45/ariane133

[wponghiran]

Hi! I am trying to replicate flow 2 with ariane133 design and NanGate45 technology. I setup a proper tool similar to first few lines in MacroPlacement/Flows/NanGate45/ariane133/scripts/cadence/run.sh and start Genus iSpatial for logic synthesis.

The error happens after syn_opt -spatial command. Following is the genus.log for the reference. Is there any additional step to perform before running this flow?

@file(run_genus_hybrid.tcl) 114: if {[info exist ::env(PHY_SYNTH)] && $::env(PHY_SYNTH) == 1} {
    syn_opt -spatial
} else {
    syn_opt
}
Synthesis config is 'syn_opt_ispatial_standard'
(ispatial): Updating setting for 'time_recovery_arcs' to match physical environment.
(syn_opt_placed): Activating iSpatial - opt_spatial_effort standard

Similar issue also happens for ariane133 design and ASAP7 technology.
