1. I got the following error when I started modelsim in ISE.
Loading work.tb_ic1_func
# ** Error: (vsim-19) Failed to access library 'xilinxcorelib_ver' at "xilinxcorelib_ver".
# No such file or directory. (errno = ENOENT)
# ** Error: (vsim-19) Failed to access library 'unisims_ver' at "unisims_ver".
# No such file or directory. (errno = ENOENT)
# Loading work.fifoctlr_ic_v2
# ** Error: (vsim-19) Failed to access library 'xilinxcorelib_ver' at "xilinxcorelib_ver".
# No such file or directory. (errno = ENOENT)
# ** Error: (vsim-19) Failed to access library 'unisims_ver' at "unisims_ver".
# No such file or directory. (errno = ENOENT)
# ** Error: (vsim-3033) fifoctlr_ic_v2.v(126): InstanTIaTIon of 'BUFGP' failed. The design unit was not found.
what is the reason?
"Point to the simulation mode, select the chip you set up the project in the source, then look at the Processes, click open, there is a compile HDL simulaTIon library, run it and it will be OK"
2. ISE uses modelsim simulation tips: # ** Error: (vish-4014) No objects found matching '*'. The result is always an error when simulating:
# ** Error: (vish-4014) No objects found matching '*'.
# Error in macro ./test_top_tb.fdo line 10
# (vish-4014) No objects found matching '*'.
# while execuTIng
# "add wave *"
Solution, change a parameter in the modelsim.ini file: VoptFlow = 0
3. When the IP core is modified, it is simulated by Modelsim: No entity is bound for inst or CE is not in the entity. (CE is a pin added after the change), so the simulation has no result.
Solution: First select the .xco file of the IP core and right click -> Properties to change the attribute to "Synthesis/Imp + Simulation."
Then change the properties of its corresponding .v or .vhd file to "Synthesis/Imp + Simulation."
4. After starting modelsim, there is no error, but there is warning: (vsim-3009) [TSCALE] - Module 'ODDR' does not have a `timescale directive in effect, but previous modules do. The input signal is correct, the IP core is called. Or the output of the primitive is high impedance.
Solution: The library that calls the IP core or primitive in modelsim does not match. Find the library unisims in xilinx and recompile it into the UNISIMS_VER library of modelsim. The problem can be solved.
24 hours mechanical Timer
Instant indicator
Min.setting time:15 minutes. Max.setting timer:24 hours
With hand switch,can be switched to operating and
setting at any time
Instructions:
1. Set program: 1 pin is equivalent to 15 minutes. Determine desired start time and push down pins until desired
off time.
For instance, if you want electrical devices to work from 8:00am to 11:00am and from 13:00pm to 17:00pm, you
just need to put down allthe pins between the three period time.
2. Set the current time: Turning the dial clockwise until the arrow pointing to
current time.
For example,if now it is 8:00 am, please turn the dial and make sure the
arrow point to 8. (See the picture.)
3. Plug the electrical device directly into the timer. Make sure the electrical
device is power-on.
4. Plug the timer into electrical outlet and the electrical device will be work
according to the setting program.
Note: = Normal Ope n = Timing
Make sure the switch on the Timing position. If it
is on the [Normal Open" mode, the electrical device is
always power-on and the timer function no work.

Application:
1. To enable high-power electric appliances to run automatically at off-peak time if there is different electricity
price according to different periods of time in some areas.
2. To use for electric appliances which need time control, such as water heaters, air conditioners, drinking
fountains, rice cookers, advertising lights and so on.
3. To control the charging time. For example, battery of electric bikes or mobile phones, storage batteries, etc.
4. Occasions which need switch on/off frequently, like interval spray irrigation for flowersand lawn, cyclical
adding oxygen to fish jar, fountains and so on.
5. Home safety precautions and lighting.
Caution:
1.D o not exceed the maximum ratings of the timer.
2.M ust reset the current time after power failure.
3.D o not plug the timer directly into the working electrical appliances.
4.U nless changing the setting, keep the program same every day.
5.D o not disassemble timer by yourself. Professionals service are needed for maintenance.
6.T his item is only for indoor use.
