Maximum limit reached for tcpwm

[vanditasharma]

Hey,

We are using PSOC6 CY8C6347BZI-BLD53 for our product. I am trying to add additional timer counter blocks (tcpwm) which will bring our in project use to 27 timers. The chip has 32 blocks available. I get this error upon enabling the 23rd timer block

E2810: The solution search limit for pin and fixed function block placement has been exceeded.

Attaching a screenshot for the full error. When I only have 22 timers, the error goes away so I know it is the TCPWM block and no other components.

Is there a way to know if the other blocks are used elsewhere internally? We have BLE enabled alongwith several other blocks including wdt, spi, i2c, uart etc.

Thanks in advance,

Vandita

Hello, 

You can add 32 timers for CY8C6347BZI-BLD53 Chip. Please refer to the attached project where I added  32 timers in the project. 

Could you please share your project for checking at our end ?

Update: The reason for getting this error message is because of the limitation on the number of inputs a TCPWM block can get. Each TCPWM block can get 14 inputs(In the Architecture TRM ("Trigger Multiplexer Block" figure 24-4), it shows the amount of trigger signals per peripheral).
Reducing the TCPWMs and come up with another circuit design solves the problem.

Thanks,

Hey Yugandhar,

Thank you for your reply. I can't share the project here. I went through the datasheet and I see that there are 24 16 bit timers and 8 32 bit ones. I was using all 16 bit timers so I will try to change that and see if that helps. I'll report back here and start a private ticket if I can't find a resolution.

Thanks,

Vandita
