Waveform Data Type (WDT)
[array2file]
1. for 1D/2D array 'write to spreadsheet file.vi'
pro: easily processed by excel/matlab etc.
con: only 1D/2D array, additional process needed for some image application, e.g. row/column/frame 3D array
2. for n-D array 'array to spreadsheet string.vi' & 'write to text file.vi'
pro:
clear header for every subset of the whole array
can be easily readout by labview 'spreadsheet string to array.vi'
con:
additional process required for importing to Matlab
[Mathscript RT]
support 2D array/functions only by Ver. 2017
e.g. a=zeros(2,3,4) is not support
really annoying in image processing, e.g. row/column/frame

well proximity effect
Well Proximity Effect
[intro]
implanting N-Well causes Vt increasing near N-Well edges.
The implanting particles above the N-Well edges are clustered at the N-Well edges, i.e. the concentration near N-Well edges are higher than that in the center of the N-Well.
[Environment]
BSIM 4.5 or above
in 90nm/65nm or above CMOS process
[Solution]
Pre-sim:
Cadence: Enable 'Well Proximity Accurate' option for every MOS
HSpice: set SC variable,
e.g.: M1 VD VG VS VB NMOS L=0.5U W=2U SC=2u
Layout:
increase the space between N-Well edges and MOSes according to DRC rules or above 3um.
inserting dummy source/drain for sensitive MOSes.
