SCAPIN(1) CAO-VLSI Reference Manual SCAPIN(1) 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 Out- put_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 con- trol 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 op- tion 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.
