ncsim仿真VHDL

1、文件列表

ctrl.vhd

design_io.vhd

tb.vhd

compile.nc

simulate.nc

./shm/shmtb.tcl

2、 Compile你的VHDL设计文件[compile.nc]

 #!/bin/csh -f
 #----------------------------------------------------------------------

 # ------------------------------------------------------------------- #
 # Directories location
 # ------------------------------------------------------------------- #

 setenv src_dir ../src
 setenv tb_dir  ./
 setenv work_dir ./lib

 # ------------------------------------------------------------------- #
 # Library creation
 # ------------------------------------------------------------------- #

 setenv CDS_VHDL /user/EDA_Tools/Cadence/IUS_11.10_lnx86/tools.lnx86/inca

 echo "softinclude $CDS_VHDL/files/cds.lib" > cds.lib
 echo "define work ./lib" >> cds.lib
 echo " " > hdl.var
 mkdir -p $work_dir

 # Compile Key Expander
 #
 ncvhdl -v93 -work work $src_dir/ctrl.vhd 

 #
 # Compile Testbench
 #
 ncvhdl -v93 -work work $tb_dir/design_io.vhd
 ncvhdl -v93 -work work $tb_dir/tb.vhd

compile.nc

3、simulate生成波形[simulate.nc]

 #!/bin/csh -f
 #----------------------------------------------------------------------
 # ------------------------------------------------------------------- #
 # Elaborating the Design
 # ------------------------------------------------------------------- #

 ncelab -work work work.tb:beh -access wrc

 # ******************************************************************* #
 # ------------------------------------------------------------------- #
 # Simulating the Design
 # ------------------------------------------------------------------- #

 ncsim tb +acssce+rwc -MESSAGES -input ./shm/shmtb.tcl

simulate.nc

4、Tcl脚本文件控制生成波形[./shm/shmtb.tcl]

 #生成VCD文件
 database -open ./waves/tbvcdwaves -vcd -default
 probe -create beh -depth all -all -vcd -database ./waves/tbvcdwaves

 #生成shm文件
 database -open ./waves/tbwaves -shm -default
 probe -create beh -depth all -all -shm -database ./waves/tbwaves
 run
 exit

shmtb.tcl

5、 运行脚本run[run]

注意将相关文件权限更新为可执行

 ./compile.nc
 ./simulate.nc

run

6、使用simvison查看波形

simvision ./waves/tbwaves.shm/tbwaves.trn &
