UM-176 6 - SystemC simulation Debugging the design Viewable SystemC objects ModelSim SE User’s Manual You can debug SystemC designs using all of ModelSim’s debugging features, with the exception of the Dataflow window. Objects which may be viewed in SystemC for debugging purposes are as shown in the following table. Channels Ports Variables Aggregates sc_signal sc_signal_rv sc_signal_resolved sc_clock (a hierarchical channel) sc_mutex sc_fifo sc_in sc_out sc_inout sc_in_rv sc_out_rv sc_inout_rv sc_in_resolved sc_out_resolved sc_inout_resolved sc_in_clk sc_out_clk sc_inout_clk sc_fifo_in sc_fifo_out Module member variables of all C++ and SystemC built-in types (listed in the Types list below) are supported. Aggregates of SystemC signals or ports. Only three types of aggregates are supported for debug: struct class array
Waveform compare Debugging the design UM-177 Types () of the objects which may be viewed for debugging are the following: Types bool, sc_bit sc_logic sc_bv sc_lv sc_int sc_uint sc_fix sc_fix_fast sc_fixed sc_fixed_fast sc_ufix sc_ufix_fast sc_ufixed sc_ufixed_fast sc_signed sc_unsigned char, unsigned char int, unsigned int short, unsigned short long, unsigned long sc_bigint sc_biguint sc_ufixed short, unsigned short long long, unsigned long long float double enum pointer class struct union bit_fields Waveform compare supports the viewing of SystemC signals and variables. You can compare SystemC objects to SystemC, Verilog or VHDL objects. For pure SystemC compares, you can compare any two signals that match type and size exactly; for C/C++ types and some SystemC types, sign is ignored for compares. Thus, you can compare char to unsigned char or sc_signed to sc_unsigned. All SystemC fixed-point types may be mixed as long as the total number of bits and the number of integer bits match.
