(spray diodes), but synthesis works fine with DIODE_INSERTION_STRATEGY = 3
(FastRoute's antenna avoidance). It failed saying [WARNING DPL-0005] Overlap check failed (14269)
. My main question: If I can't use DIODE_INSERTION_STRATEGY = 1
, is there some easy way I can just guarantee that every input pin has diodes? Or will they all already have diodes?
2. Secondly, I see these reported in manufacturability_report.rpt
(again, synthesizing with DIODE_INSERTION_STRATEGY = 3
):
Antenna Summary:
Source: /openLANE_flow/designs/snproc/runs/run7_rev2_mem512/reports/routing//41-antenna.rpt
Number of pins violated: 960
Number of nets violated: 651
How scared should I be of that?
results/lvs/
directory that contains some log files reassuring me that no mismatches were found. Are these checks performed on the final GDS all the way back to the first netlist? If not, do folks have advice on running an LVS, and which is the best netlist to LVS the GDS against?
