下面的编译成功了但是仿真的时候遇到fatal simulation error encountered跳转之后就这个问题想知道哪里有问题怎么解决
[SPICE] TRAN:  Timestep too small; timestep = 1.25e-019: trouble with node #00046.

单片机源程序如下:
#include <reg51.h>
#define uchar unsigned char
#define uint unsigned int
#define ulong unsigned long

xdata uchar GPS_Buffer[500]  _at_  0X0000;

xdata uchar GPRS_Buffer[500]  _at_  0X01F4;
sbit YCIN_Flag = 0xD5;
sbit Alarm_EN= P2^0;
sbit GPRS_EN= P2^1;
void EX_lnit()
{
EX0=1;
IT0=1;
PX0 = 1;
EX1=1;
IT1=0;
}
void UART_lnit()
{
;
}
void delay()
{
;
}
void GPS_Rec()
{
;
}
void GPRS_Rec()
{
;
}
void GPRS_Dec()
{
;
}
void GPRS_Comm()
{
;
}
void EX0_int( ) interrupt 0 using 1
{
GPRS_EN = 1;
delay( );
GPRS_Rec();
GPRS_Dec();
GPRS_Comm();
}
void EX1_int( ) interrupt 2 using 2
{
if( Alarm_EN == 0)
{
   Alarm_EN = 1;
}
GPRS_EN = 0;
GPS_Rec();
}
void main(void)
{
SP=0X50;
YCIN_Flag = 0;
GPRS_EN = 0;
EX_lnit();
UART_lnit();
EA=1;
// Write your code here
while (1)
{
   if(YCIN_Flag)
   {
      if(Alarm_EN ==0)
      {
         Alarm_EN = 1;
      }
      GPRS_EN = 0;
      GPS_Rec();
   }
}
}
