使用教材 《systemc入门》《systemc片上系统设计》
三、SystemC 数据类型
- sc_uint sc_int SystemC中引入了sc_int和sc_uint来实现1到64比特中任意宽度的整数数据类型，又引入了sc_bigint和sc_biguint来实现任意宽度的整数类型
二、make: `main.run.x' is up to date.
make clean
make
一、systemC 2.2 被舍弃的特性
在systemC新版本中（2.2，现在已经到2.3.0）有一些特性应经不用或者有所改变，而一般的教材由于编写年代的问题一般是基于systemC 2.0。所以在执行书中或者PPT中的例子时常会出许多警告。比如
error: no matching function for call to ‘sc_start(int)’ 解决方法如下：
1 sc_start(-1);2 which is now deprecated, you should write 3 sc_start();
error: ‘class sc_core::vcd_trace_file’ has no member named ‘sc_set_vcd_time_unit’
Still supported in 2.2. The class vcd_trace_file is now considered to be an implementation detail rather than part of the standard, so its public methods have been deprecated. You should use method set_time_unit() of class sc_trace_file instead. For example:
1 sc_trace_file* tf;2 tf = sc_create_vcd_trace_file("foo");3 tf->set_time_unit(1, SC_NS);4 // ((vcd_trace_file*)tf)->sc_set_vcd_time_unit(-9); // Deprecated 仍有许多这样的情况，在此没有一一列举出，可以参考Dealing with Deprecated Features in SystemC 2.2
