hi,
We found in the s25fl512.v and s25fl256s.v define SPEEDSIM have the same define value with no-define SPEEDSIM.
And it takes so long time to run the simulation if the SPEEDSIM didn't work.
The code is below.
`ifdef SPEEDSIM
// Page Program Operation
specparam tdevice_PP_256 = 55e7;//tPP
// Page Program Operation
specparam tdevice_PP_512 = 75e7;//tPP
// Typical Byte Programming Time
specparam tdevice_BP = 4e8;//tBP
// Sector Erase Operation
specparam tdevice_SE = 1875e7;//tSE
// Bulk Erase Operation
specparam tdevice_BE = 460e9;//tBE
// WRR Cycle Time
specparam tdevice_WRR = 2e9;//tW
// Erase Suspend/Erase Resume Time
specparam tdevice_ERSSUSP = 40e6;//tESL
// Program Suspend/Program Resume Time
specparam tdevice_PRGSUSP = 40e6;//
// VCC (min) to CS# Low
specparam tdevice_PU = 3e8;//tPU
// PPB Erase Time
specparam tdevice_PPBERASE = 15e9;//
// Password Unlock Time
specparam tdevice_PASSULCK = 1e6;//
// Password Unlock to Password Unlock Time
specparam tdevice_PASSACC = 100e6;
`else
// Page Program Operation
specparam tdevice_PP_256 = 55e7;//tPP
// Page Program Operation
specparam tdevice_PP_512 = 75e7;//tPP
// Typical Byte Programming Time
specparam tdevice_BP = 4e8;//tBP
// Sector Erase Operation
specparam tdevice_SE = 1875e9;//tSE
// Bulk Erase Operation
specparam tdevice_BE = 460e12;//tBE
// WRR Cycle Time
specparam tdevice_WRR = 2e11;//tW
// Erase Suspend/Erase Resume Time
specparam tdevice_ERSSUSP = 40e6;//tESL
// Program Suspend/Program Resume Time
specparam tdevice_PRGSUSP = 40e6;//
// VCC (min) to CS# Low
specparam tdevice_PU = 3e8;//tPU
// PPB Erase Time
specparam tdevice_PPBERASE = 15e9;//
// Password Unlock Time
specparam tdevice_PASSULCK = 1e6;//
// Password Unlock to Password Unlock Time
specparam tdevice_PASSACC = 100e6;
`endif // SPEEDSIM
So we need the correct vaule to speed up our simulation, tks.

Hello,
We would like to get some more details about this issue.
1. What is the version of Verilog model (s25fl512.v) that you use in your simulations?
2. Are you using SDF file for simulation?
Thanks and Regards,
Sudheesh

Hello,
The latest version on the Verilog model for our device S25FL512S is 2.16. It is available at: https://www.cypress.com/verilog/s25fl512s-verilog .
- Could you please use this latest model for your simulation?
- Use SDF file for your simulations and check if the error goes away.
Thanks and Regards,
Sudheesh

Hi,
We downloaded the latest model, and that is v2.16, but still have the same problem.
SDF file seems won’t work, tks.
