Hspice 中EBD用法

zhaojizhi

Hspice中自带的EBD例子
_IO_cmpnt1
+ file="ebd.ibs"
+ component="component1"
.connect _io_cmpnt1_1_d_drive   vdd ! ignored
.connect _io_cmpnt1_1_d_enable  vss ! input buffer
.connect _io_cmpnt1_1_d_receive _io_cmpnt1_2_d_drive
.connect _io_cmpnt1_2_d_enable  vdd ! output buffer

_IO_cmpnt2
+ file="ebd.ibs"
+ component="component1"
.connect _io_cmpnt2_1_d_drive   vdd ! ignored
.connect _io_cmpnt2_1_d_enable  vss ! input buffer
.connect _io_cmpnt2_1_d_receive _io_cmpnt2_2_d_drive
.connect _io_cmpnt2_2_d_enable  vdd ! output buffer

_IO_ebd1 file="ebd.ebd"
+ ebd_model="EBD1"
+ ref_des_map='u1=_IO_cmpnt1'
+ ref_des_map='u2=_IO_cmpnt2'
Vtest _IO_ebd1_1 0 PULSE ('VSS' 'VDD' 1n 1n 1n 9n 20n) ! input signal
Rload _IO_ebd1_5 0 50.0  ! output signal

请问，_IO_cmpnt2在Hspice中代表什么？用.ibis和.ebd这两个command是不是也可以实现仿真？
