encrypt_eldo Tool
• .INLINE/.ENDINLINE act as .SUBCKT/.ENDS. The inline block is encrypted in the
same way as subcircuits; it does not require the -veriloga argument.
• For partial encyrption, use the Verilog-A source code directives `pragma protect begin
\ `pragma protect end, `protect \ `endprotect, or `protect begin \ `protect end, to
specify the blocks for protection inside the Verilog-A model file.
• By default -veriloga encrypts the complete file, except the lines containing the keywords
module, macromodule, endmacromodule, endmodule.
