SystemClock_config() timeout while using the keil Simulator - microcontroller

Question

In this example I will use SPI2 run in mode Master(NSS pin control by software) to send data.
SPI3 run in mode Slave (NSS pin control by harware) receive data using DMA.
PC2 (SPI2 MISO) connect to PC11(SPI3 MISO).
PC3 (SPI2 MOSI) connect to PC12(SPI3 MOSI).
PB10 (SPI2 SCK) connect to PC10 (SPI3 SCK).
PC6 (SPI2 NSS pin control by sofware) connect to PA4(SPI3 NSS pin control by hardware).

During debugging, I found that SystemClock_config() function continuously running given below code.
/* Wait till HSE is ready */
while(__HAL_RCC_GET_FLAG(RCC_FLAG_HSERDY) == RESET)
{
if((HAL_GetTick() - tickstart ) > HSE_TIMEOUT_VALUE)
{
return HAL_TIMEOUT;
}
why is it not going to further function?

If you are using RTOS this could help:
http://www.keil.com/support/docs/3931.htm
Therefore the CMSIS RTOS already configures the priorities for some interrupts. Try to uncomment following code from SystemClock_Config() additionally to the description:
//HAL_SYSTICK_Config(HAL_RCC_GetHCLKFreq()/1000);
//HAL_SYSTICK_CLKSourceConfig(SYSTICK_CLKSOURCE_HCLK);
/* SysTick_IRQn interrupt configuration */
//HAL_NVIC_SetPriority(SysTick_IRQn, 0, 0);
I hope it helps.
