I am trying to get some logic gates working in kicad-simulation following this Tutorial.
I downloaded the 74HCng.lib as described in the above link, and set this library, and the appropriate model (74HC00) for my component in the spice-model-editor.
The spice-model consists of the following:
.param vcc=5 tripdt=6n *********************************************************************************** * The 74HCXX gates * * 2-input NAND gate * vcc 2 /4.5/5 /6 * tpd 25n/9n/7n/7n * tr 19n/7n / /6n .SUBCKT 74HC00 in1 in2 out NVCC NVGND vcc1={vcc} tripdt1={tripdt} .param td1={1e-9*(9-3-3)*4.0/(vcc1-0.5)} .param Rout={60*4.0/(vcc1-0.5)} $ standard output driver *Cin1 in1 0 3.5p *Cin2 in2 0 3.5p abridge2 [in1 in2] [din1 din2] adc_buff .model adc_buff adc_bridge(in_low = {vcc1/2.0} in_high = {vcc1/2.0}) a6 [din1 din2] dout nand1 .model nand1 d_nand(rise_delay = {td1} fall_delay = {td1} + input_load = 0.5e-12) abridge1 [dout] [out20] dac1 .model dac1 dac_bridge(out_low = 0.0 out_high = {vcc1} out_undef = {vcc1/2.0} + input_load = 5.0e-12 t_rise = {tripdt1} + t_fall = {tripdt1}) Rout out20 out {Rout} .ends Note that I only understand very little about spice..
Anyway, I connect the gate in the following, very basic circuit: Note that the value "3" at the NAND-gate is just me trying to somehow get the right parameters for running a simulation (I don't really know what value is expected there - my first instinct is that a threshhold-voltage would make sense there - so i plugged in 3 for 3 Volts) 
Then I annotate the schematic, open the simulator, plug in 10n time-step and 1u final time for the transient-settings, and try to run the simulation. Unfortunately, kicad tells me:
Circuit: KiCad schematic Too few parameters for subcircuit type "74hc00" (instance: xxu1) Background thread stopped with timeout = 0 Error: there aren't any circuits loaded.
Okay, so it seems I am not providing enough parameters. But I don't know what parameters I am missing to provide, or where I have to provide them... I hope that someone a bit more versed in spice and kicad might be able to point me into the right direction here.
