https://easyeda.com/ashah140/temp-0060e7c04d904ed78c2fd969147762f6 My simulation got failed and I have checked all possibilities as per previous posts but could not resolve issue. So please help me to solve one. I put this project on public mode. Here is the netlist for it. good* no system model for CSD18532KCS, you can create a model by yourselfUntitled V2 R5_2 GND 3.3V V1 C2_1 GND 16V RSNS C2_1 U1_1 4m RPWR GND RPWR_2 15.8k R5 U1_8 R5_2 100k R4 GND U1_4 4.22k R3 U1_4 C2_1 47.5k R2 GND U1_3 8.25k R1 U1_3 C2_1 47.5k Q2 Q2_1 U1_1 VOLPROBE1 CSD18532KCS CTIMER A GND 1u C2 C2_1 GND 1u C1 VOLPROBE1 GND 1u .param pi = 3.141593 .func LIMIT(x, y, z) {min(max(x, min(y, z)), max(z, y))} .func PWR(x,a) {(MAX(ABS(x), 1e-313))**a} .func PWRS(x,a) {sgn(x) * PWR(x,a)} .func stp(x) {u(x)} .func log10(x) {ln(x)/ln(10)} .func SQRT(x) {(MAX(x, 1e-313))**0.5} .func INT(x) {sgn(x)*floor(ABS(x))} .func URAMP(x) {max(x,0)} .func POW(x,a) + {(((a-(int(a)))==0)||(sgn(x)>=0))*( max(exp(ln(uramp(x))*a),0) + + (2*(0.5-ABS((int(a))-2*int(a/2))))*max(exp(ln(uramp(-1*x))*a),0) )} .control tran 1u 1m 0 probe V(VOLPROBE1) quit .endc .END
