Hello everyone,
I’ve just started learning how to use Xilinx products. I have created a simple IP to calculate a function on the image.
"#include
float calculer_tension(float resistance, float intensite) {
float tension;
tension = resistance * intensite;
return tension;
}
int main() {
float resistance, intensite, tension;
std::cout << "Entrez la valeur de la résistance (en ohms) : ";
std::cin >> resistance;
std::cout << "Entrez la valeur de l'intensité (en ampères) : ";
std::cin >> intensite;
tension = calculer_tension(resistance, intensite);
std::cout << "La tension est de " << tension << " volts.\n";
return 0;
}"
I obtained the IP that I integrated into Vivado. I want feedback on the LED_PORT. I get an error after generating the Bitstream as shown in the image. Can you help me fix this please?
[DRC UCIO-1] Unconstrained Logical Port: 32 out of 162 logical ports have no user assigned specific location constraint (LOC). This may cause I/O contention or incompatibility with the board power or connectivity affecting performance, signal integrity or in extreme cases cause damage to the device or the components to which it is connected. To correct this violation, specify all pin locations. This design will fail to generate a bitstream unless all logical ports have a user specified site LOC constraint defined. To allow bitstream creation with unspecified pin locations (not recommended), use this command: set_property SEVERITY {Warning} [get_drc_checks UCIO-1]. NOTE: When using the Vivado Runs infrastructure (e.g. launch_runs Tcl command), add this command to a .tcl file and add that file as a pre-hook for write_bitstream step for the implementation run. Problem ports: LED_PORT[31:0].
Thanks
