NAME
scapin - Scan path insertion
SYNOPSIS
scapin [-VRB] [-P file] Input_name Path_name Output_name
DESCRIPTION
SCAPIN is an automatic scan path generator for gate level netlists. SCAPIN inserts a scan
path in the netlist Input_name and drives a new netlist Output_name. This scan path
contains all registers specified in the file Path_name.path (see below for the exact
syntax). SCAPIN adds also 3 new connectors in the netlist: scan_in, scan_out and
scan_test in order to control the scan path. Eventually SCAPIN adds an output buffer
before the output connector scan_out (option -B).
ENVIRONMENT VARIABLES
MBK_WORK_LIB(1)
indicates the path to the read/write directory for the session.
MBK_IN_LO(1)
indicates the input netlist file format.
MBK_OUT_LO(1)
indicates the output netlist file format.
SCAPIN_PARAM_NAME
indicates the location of a parameter file (with extention .scapin) containing
the properties (ports name, models name etc ...) of all cells needed for the
scan path insertion. (see below for the exact syntax)
OPTIONS
-V Sets verbose mode on. Each step is displayed on the standard output.
-R All registers of the scan path are replaced by an equivalent scannable register
cell (called reg-mux). (With the default option a simple multiplexor is added
just before all registers of the scan path).
-B Adds an output buffer before the output connector scan_out.
-P file Specifies a parameter file (with extention .scapin) containing the properties of
all cells needed for the scan path insertion. (see below for the exact syntax)

Path_name Specifies a parameter file (with extention .path) containing an ordered list of
all instances (registers) of the scan path. It contains also the name of the 3
connectors scan_in, scan_out and scan_test. (see below for the exact syntax)
