+This is a list of 'modifications' to the standard Calibre verification flow I
+have used in the past to either modify the checks performed by Calibre or input
+data bases.
+
+# DRC
+
+## Extended Device Checks
+
+```tvf
+NVA0.VAR_OVLP { @ Varactors / Tiles should not overlap
+    VARi AND > 1
+}
+```
+
+```tvf
+NVA1.Cu_PPI.TEAR { @  Shape of Cu_PP I pad (under PM2 area): tear shape required
+  X0 = EXT Cu_PPIi <1 ABUT <125 INTERSECTING ONLY REGION
+  X1 = EXT Cu_PPIi <1 ABUT <180 INTERSECTING ONLY REGION
+  X2 = INT Cu_PPIi <1 ABUT <180 INTERSECTING ONLY REGION
+  X3 = EXPAND EDGE (X1 NOT TOUCH INSIDE EDGE X0) BY 1 EXTEND BY 50
+  X4 = EXPAND EDGE (X2 NOT TOUCH INSIDE EDGE X0) BY 1 EXTEND BY 50
+  (X3 AND X0) OR (X4 AND X0)
+}
+```
+
+
+## Layer / Device Aliasing
+
+```tvf
+LAYER MAP 107 DATATYPE 0 746
+```
+
+# LVS
+
+## Adding New Device Primitives
+
+```tvf
+LAYER RESLYR          450
+LAYER MAP 215 DATATYPE 21 450 //  layer to form memresistor
+XTERM = RESLYR AND M4
+XCDTR = RESLYR NOT M4
+CONNECT metal4 MEMRESLYRT
+DEVICE XDEVICE XCDTR XTERM(PORT1) XTERM(PORT2) netlist model xdevice
+```
+
+```spice
+.SUBCKT xdevice PORT1 PORT2
+.ENDS
+```
+
+```lisp
+(xdevice
+  (DEVICE_LIB DEVICE_CELL DEVICE_VIEW)
+  (
+    (PORT1 PIN1)
+    (PORT2 PIN2)
+  )
+  (
+    (nil multi 1)
+    (nil m 1)
+  )
+)
+```
+
+## Extending Connectivity Layers
+
+```tvf
+LAYER PM1i 5001
+LAYER MAP 5 DATATYPE 1 5001
+LAYER Cu_PPIi 7410
+LAYER MAP 74 DATATYPE 10 7410
+LAYER UBM 170
+LAYER MAP 170 DATATYPE 0 170
+LAYER PM2i 5002
+LAYER MAP 5 DATATYPE 2 5002
+VIA8 = COPY CB2
+metal9 = COPY Cu_PPIi
+VIA9 = COPY PM2i
+metal10 = COPY UBM
+CONNECT metal9 metal8 BY VIA8
+CONNECT metal10 metal9 BY VIA9
+TEXT LAYER 140 ATTACH 140 metal9
+PORT LAYER TEXT 140
+TEXT LAYER 141 ATTACH 141 metal10
+PORT LAYER TEXT 141
+TEXT LAYER 125 ATTACH 125 metal10
+PORT LAYER TEXT 125
+```
+
+## Hot fixing LVS comparison
+
+```tvf
+LVS SPICE CULL PRIMITIVE SUBCIRCUITS YES
+VIRTUAL CONNECT NAME "POWER"
+TEXT "POWER" LOCX LOCY DATATYPE
+LAYOUT RENAME TEXT "/DATA\\[(.*)\\]/DATA<-1>/M-"
+```
+

+
+# SPICE
+
+## Port Order Reshuffling
+
+```bash
+function getSortedOrder() {

+            | sort -k 1,1 -k2,2nr | sed -r "s/ ([0-9]+) /\[\1\]/g" ))
+  else
+    SORTED=($(echo "${SOURCE[@]:2}" | tr " " "\n" | sed -r "s/<([0-9]+)>/ \1 /g" \
+            | sort -k 1,1 -k2,2nr | sed -r "s/ ([0-9]+) /<\1>/g" ))
+  fi
+  echo "${SOURCE[@]:0:2} ${SORTED[@]}"
+}
+function updatePortOrder() {
+  local TARGET="$1"
+  local CDL_FILE="$2"
+  local PORTORDER="$(awk -v target="subckt ${TARGET} " -f "catch.awk" "$CDL_FILE")"

+      && echo "Error $CDL_FILE uses mixed delimiters"
+}
+```
+
+```awk
