does anybody give me H-SPICE code in HBM mosel for ESD device

[vishal_meshram1087]

plz give me H-SPICE code for HBM model for ESD

 

[erikl]

Something like this?

[FONT=Courier New].param		HV=4kV

V_HV		hv  0 'HV'
R_load		hv c0 10Meg
C_load		c0  0 100p
V_ctrl		c1  0 PWL (0 0V .99u .001V 1u 1V) 
G_switch	c0 HBM_out VCR PWL(1) c1 0 0V,100G 1V,1500

.tran		10n 2u[/FONT]

Hi Erikl， the transient time you chose，like 1u、2u， is that the standard of HBM？

Re: does anybody give me H-SPICE code in HBM model for ESD device

No, the times used are just adapted to the load time constant of the test capacitor C_load (1MΩ*100pF=100µs) and the discharge time constant of the HBM (1500Ω*100pF=150ns, which is standard for the HBM). See this PDF: View attachment HBM.pdf

Transient analysis stop time for this simulation should be 1.001ms , not 2µs as shown above.

Thank you very much！
I see，you set 1.001ms to achieve enough time for charging and discharging.
Could you tell me the name of the software you used？
Can VCR replace the switch that in your schematic？in spectreRF

For that HBM.pdf above? This was Qucs: Quite useful circuit simulator. Free SPICE-type tool.

Yes, I think so.
