Hello! Does anyone know why I might have LVS errors in precheck? I attach the LVS precheck log and the user project wrapper configuration file.

The log file has

LVS result:
Final result: 
Circuits match uniquely.
.
LVS Done.
Warning: device level LVS may be incomplete due to 2 unflattened cell(s): see /home/baungarten/Desktop/HW_TI_Encryption/precheck_results/01_NOV_2023___00_25_59/outputs/reports/lvs.unflattened

If you open,

lvs.unflattened

, you’ll probably see your 2 macros -

aes_Trojan

and

des_Trojan

. Currently, your

lvs/user_project_wrappper/lvs_config.json

file probably has the default

"LVS_VERILOG_FILES": [
                "$UPRJ_ROOT/verilog/gl/user_proj_example.v",
                "$UPRJ_ROOT/verilog/gl/user_project_wrapper.v"
        ],

If your gate level verilog for these macros is in

verilog/gl

,

lvs.unflattened shows:

aes_Trojan is a black box in the source
des_Trojan is a black box in the source

and "lvs/user_project_wrappper/lvs_config.json" shows:

"LVS_VERILOG_FILES": [
		"$UPRJ_ROOT/verilog/gl/user_proj_example.v",
		"$UPRJ_ROOT/verilog/gl/$TOP_SOURCE.v"
	],

does the $TOP_SOURCE.v isn't work? or why it happens now and in previos precheck didnt it? I will try with it, but the precheck takes time.

"LVS_VERILOG_FILES": [
                "$UPRJ_ROOT/verilog/gl/aes_Trojan.v",
                "$UPRJ_ROOT/verilog/gl/des_Trojan.v", 
                "$UPRJ_ROOT/verilog/gl/user_project_wrapper.v"
        ],

Full device level LVS is a new addition to precheck.

It still give me the LVS error. I changed the

lvs/user_project_wrappper/lvs_config.json

with:

"LVS_VERILOG_FILES": [
	        "$UPRJ_ROOT/verilog/gl/aes_Trojan.v",
                "$UPRJ_ROOT/verilog/gl/des_Trojan.v", 
		"$UPRJ_ROOT/verilog/gl/user_proj_example.v"
	],

The message

Warning: device level LVS may be incomplete due to 2 unflattened

didn't appears. What could be wrong?

You’re missing

user_project_wrapper.v

. Looks like there’s

user_proj_example.v

instead.

user_proj_example

isn’t used , is it?

Sorry, i try it yesterday at nigth and i didn´t see that mistake, let me run it again.
