## 快速开始
`LAB` ：实验序号，可选值[1,2,3,4]
### 第一次编译
```bash
make all GENLIB=1
make all LAB=1 GENLIB=1
```
### 第二次编译
```bash
make all GENLIB=0
make all LAB=1 GENLIB=0
```
## 运行结果
```
Top Level Modules:
testbench
TimeScale is 1 ns / 1 ps
Note-[PC_SHARED] Reusing shared partition
Reusing partition '_vcs_pc_package_' from shared library './partitionlib'.
Note-[PC_SHARED] Reusing shared partition
Reusing partition 'uvm_pkg' from shared library './partitionlib'.
Note-[PC_SHARED] Reusing shared partition
Reusing partition 'counter_a' from shared library './partitionlib'.
Warning-[PC_NOT_SHARED] Cannot reuse shared partition
Cannot reuse partition 'counter_b' from shared library './partitionlib'
There are additional signals that are now targets of hierarchical
references.
Note-[PC_GEN_PARTITION] Generating partition
Generating new partition 'counter_b' at
'./partitionlib_test2/counter_b_ipFRWc'.
Warning-[PC_NOT_SHARED] Cannot reuse shared partition
Cannot reuse partition 'counter_c' from shared library './partitionlib'
There are additional signals that are now targets of hierarchical
references.
Note-[PC_GEN_PARTITION] Generating partition
Generating new partition 'counter_c' at

Note-[PC_SHARED] Reusing shared partition
Reusing partition 'top' from shared library './partitionlib'.
Warning-[PC_NOT_SHARED] Cannot reuse shared partition

Modified Design Units :
TB.testbench : "./rtl/testbench.sv", 20
Type of targets of hierarchical references in this partition have changed.
Note-[PC_RECOMPILE] Recompiling partition
Recompiling partition 'TB.testbench' because of following changes.
Modified Design Units :
TB.testbench : "./rtl/testbench.sv", 20
```
检查log可以发现，穿层信号变化涉及到的模块`counter_b、counter_c`都无法reuse。
