Can userguide add the following information?

1. What kind of systemc coding can be translated into "assign" statements， for exanple "assign a = b;" ?
2. How does systemc describe bit operations, e.g. assign b[0] = a[0] & a[1]; ?

Looking forward to your reply。

Answering your questions:

1. Generally, designing in SystemC it make sense to understand which hardware will be created in ASIC/FPGA, not which SV will be generated. To assign one signal to another SC_METHOD is used in SystemC, which is normally translated into always_comb block. SC_METHOD without sensitivity is translated into assign, but right part can be a constant or literal only.
2. Bit operations implemented in SystemC integer types. See sc_uint/sc_biuint in IEEE 1666-2023.

It's all settled.
